Renewable energy sources are cleaner ways of getting energy, basically anything but burning fossil fuels. There are many renewable energy sources that we can use to reduce pollution and greenhouse gas emissions. For example, here in British Columbia, we use hydro power, which means we get our energy from water. There are many forms of renewable energy such as wind energy, geothermal energy, solar energy, and bio energy. Some well know ways of using these sources of energy are wind turbines, or solar panels. Which turn wind and sun into energy. But what if you don't have control over what energy you use? Write to government officials! Donate to organisations who work to have clean energy! If we can get the majority of the planet using renewable energy, this will lower our greenhouse gas emissions by a lot!!

Pollution is a major environmental issue affecting air, water, and soil. It is primarily caused by human activities like industrial emissions, vehicle exhaust, and improper waste disposal. Pollution harms ecosystems, endangers wildlife, and poses serious health risks to humans. Reducing pollution requires global cooperation and sustainable practices to protect our planet for future generations.

I agree that reducing pollution requires global cooperation. I think many people have a mentality that since other people wont reduce polution they wont either.

I feel very passionate about the fact that for us to calm down pollution, we all have to come together as a whole and change the things we are doing. We also have to think about other people because, in America, most people care about themselves and don't care about the people around them, which causes people to do reckless behavior.

I feel like this is an "obvious" thing to say, but It's definitely true. I think we should ask the question, "How do we convince many people on an international scale to contribute to stopping pollution?"

I like how you mentioned water and soil pollution because people are not very informed on those topics. The most discussed topic on pollution is air pollution but there's much more to it than just that. There's many more contributions to pollution that not a lot of people talk about like pollution caused by agriculture. I think that humans in general should be more educated on pollution and the way it affects so many aspects of the world from food, the ocean/marine life, air quality, health effects, and so much more. We also need to be more informed on the ways we can reduce our impacts on pollution. There's so much more to what we can do than just driving less with gas-run cars and not littering, and also the small things we can do in our daily lives to make a huge impact our how the environment turns out to be.

I want to bring up planes. I think planes are very important for life because they allow you to travel all around the world in just a few hours. I think planes are great but I think we should change something about them. We need to change the fact that planes are major polluters. Planes remain among the most polluting means of transport and something needs to be done. I propose electric planes. I have no idea how one would go about doing this, but this is just a suggestion. I want to bring this up because personally I travel and go on airplanes a lot and in return, I pollute a lot. This year, I calculated my carbon footprint and it said that it was 25,784 kgs of CO2 per year, compared to the average in California; 9,727 kgs of CO2 per year. You might be wondering why my carbon footprint is so high. It is because I travel so much. 18,311 of the 25,784 kgs of CO2 was from transportation. So overall, I think something needs to change about airplanes because I want to keep traveling but I dont want to be a major polluter.

I think create electric plane is a good idea but is almost impossible because autonomy of airplane would be greatly reduce and the weight too much .

the climatic conditions are getting worse and worse, today we should reduce the consumption of non renewable sources, reduce pollution, stop deforestation, recycle, and use renewable sources.

In this world, people are still learning about the problems for combustion engines, and transportation such as cars planes and buses that have on the for the fossil fuels to our atmosphere. All transportation run by combustion engines releases mass amounts of fossil fuels into our atmosphere, which leads to climate change due to greenhouse gasses. Planes especially have a contribution to the fuels, since they are huge and need lots of power to take off and maintain speed while flying. Also, with millions of cars on the streets daily, fossil fuels are also being released at an alarming rate. Even electric vehicles require a lot of energy to produce which causes the release of fossil fuels. There are a few possibilities to where we can fix this problem. For one, taking public transportation is one of the best ways to begin shortening our carbon footprint. Two, buying electric vehicle takes a huge step from combustion engines, which will extremely shorten our carbon footprint. Although they require a lot of energy to produce, if used long enough, they are more efficient than combustion engines. And finally, making commercial electric planes will help reduce the carbon footprint of many travelers.

Degradarea mediului înconjurător este un proces lent, dar sigur. În prezent, poluarea și epuizarea resurselor naturale reprezintă probleme ce afectează o mare parte din populația planetei.
A venit vremea să conștientizăm faptul că resursele naturale NU sunt interminabile și că orice mică acțiune pe care o exercităm asupra mediului înconjurător, cum ar fi simpla aruncare a unui ambalaj pe stradă, va avea consecințe negative.
Iată cum puteți contribui la protejarea mediului înconjurător:
1. Nu mai aruncați gunoaie pe jos!
Pentru început, adoptați un comportament ecologic prin a evita să mai aruncați gunoaiele direct pe stradă. Există recipiente speciale pentru colectarea deșeurilor, amplasate în fiecare oraș. Fiți cetățeni responsabili și încurajați reciclarea materialelor din sticlă, hârtie și plastic, plasând deșeurile în pubelele corespunzătoare.
2. Dacă dețineți o fabrică sau o firmă care poluează mediul prin arderea materiei brute, asigurați-vă că apelați la serviciile companiilor care se ocupă de colectarea și reciclarea deșeurilor industriale, cum ar fi GREENGlobal, pentru a reduce gradul de poluare.
3. Conduceți mai rar!
Mașinile poluează EXTREM de mult prin arderea combustibilului și evacuarea acelui fum negru și toxic, care este atât de nociv pentru mediul înconjurător.

Carbon footprint of students can vary greatly depending on their lifestyle and habits. However, it's crucial for students to be mindful of their environmental impact and strive to reduce their carbon footprint. Simple changes like using public transportation, reducing energy consumption, and adopting sustainable practices can make a significant difference. Moreover, educational institutions should also promote eco-friendly initiatives and provide resources to help students make more environmentally conscious choices. By collectively working towards reducing carbon emissions, students can contribute to a healthier planet for future generations.

i agree with your opinion, but the students are not careful to the Carbon Footprint.

I agree that students should try to reduce their carbon footprint and should be more mindful of their environmental impact. While I agree with that, I disagree that students should use public transportation more. I take a bus 2 miles to the train station then take the train 45 minutes to my house every day after school, this increases my carbon footprint a massive amount. My overall foot print is 25,784 kgs and my transportation carbon footprint was 18,311 kgs, which is about 70% of my overall carbon footprint. So instead of public transportation i propose to use electric cars and carpool with a friend. This will really make a difference in your carbon footprint and help overall sustain a healthy environment.

Of course I agree that reducing carbon footprint is important and I agree that changing your lifestyle can help with that. It is very frustrating for me though because when I took the test, my carbon footprint for transportation was way above average, however I don't know how to reduce it! I live far away from school but I take the bus and I have to go to sports practice everyday. I feel like I can't really reduce my transportation footprint even though I want to because most of where I go is necessary to my daily life. Overall, I want to find a way to dramatically change my carbon footprint but still get where I need to go.

I also agree that students need to be more aware of their impact in order to reduce their carbon footprint. However, I don’t believe that a small lifestyle change is necessary for all students. From my experience, the biggest carbon sink that I had was airplanes/flights as they took up half of my footprint at about 9,300 kgs. So for me, if I wanted to bring my carbon footprint down the best solution would be to fly less and not to switch to public transportation. Also in my case, I already take public transportation so I wouldn’t need to switch to using it. But, It doesn’t mean that people who don’t take public transit shouldn’t stop, only that not everyone needs to make that change as they already might be taking public transit. Depending on the person their carbon footprint may be heavily increased by different influences, therefore I agree that people can change their carbon footprint by changing something, but not everyone can change a small thing and have the same impact.

As an entire population, our world is still learning about the negative effects combustion engines and transportation have on the addition of fossil fuels to our atmosphere. All transportation run by combustion engines emits mass amounts of fossil fuels into our atmosphere, leading to climate change due to greenhouse gasses. Planes especially contribute immense amounts of fossil fuels since they are very big and require a lot of power to take off and maintain speed while flying. Additionally, with the tens of millions of cars on the streets daily, fossil fuels are being emitted at an absurd rate. Even electric vehicles require a lot of energy to produce which causes the emission of tons of fossil fuels. How can we fix this problem? There are a few possibilities... First, carpooling and taking public transportation is one of the best ways to begin minimizing your carbon footprint. For every person who contributes, we will emit less every day. Secondly, buying electric vehicles is a big step up from combustion engines, which will drastically minimize your carbon footprint. Although they require a lot of energy to produce, if used long enough, they are more efficient than combustion engines. Finally, developing commercial electric planes will immensely help reduce the carbon footprint of many travelers. Let's continue to minimize our carbon footprint and make our planet a healthier place.

Do you know why birds are showing up in the most unlikely places? That's because of climate change messing with their migration patterns, in fact warmer temperatures mess up their internal GPS, so they end up flying to different places for food and shelter. These bird migrations might not seem like a big deal, but they mess with ecosystems and can even make some species struggle to survive. So, let's keep an eye on life below our heads and work to protect their habitats.

We need to prioritize clean development by reducing our reliance on non-renewable sources of energy. Instead of burning fossil fuels like coal, oil, and natural gas, which release harmful emissions into the atmosphere, we should focus on renewable energy sources like solar, wind, and hydroelectric power.
By transitioning to renewable energy, we can not only reduce pollution and combat climate change but also create new job opportunities and stimulate economic growth in the clean energy industry. Investing in renewable energy technologies and infrastructure is key to achieving a sustainable future for our planet and future generations.

From factory emissions from fossil fuels burned by automobiles, there are many ways that our world develops. Without development we will have no technological advancements in our world. In which we constantly need to address the many problems we face in our modern world. There needs to be a form of clean energy, one which may be burned through without causing any form of environmental damage. This is true of Electricity in certain cases depending upon how it is generated. If generated via clean means (Water, Wind, Thermal via the Sun), there is no emission which can be traced back to it, nor can impact the environment. It’s one of many clean sources of energy which have no polluted or harmful emissions. These sources of energy need to be used more efficiently and often. Solar could be the most viable, as it is the most efficient and viable but is expensive and only works on a clear sunny day. In my opinion I feel that we could most definitely use more wind energy as it's free, The only problem is that it won't always be windy. So what else could we use? Short answer, all of the different energy sources.
See in my Opinion we could utilize all of them, chances are most companies don't use all of them but some are returning to a more energy efficient way to reduce emissions and keep cost low while not damaging the environment in any way.

There are multiple different ways that we can keep our environment clean, but one of the biggest ways is simply throwing away or recycling your trash. Many people don’t actually realize how much trash ruins the environment and how much it kills animals. The United States alone produces 268 million tons of waste each year, 140 million of it going into landfills. Each American throws away about 1,200 pounds of organic waste each year, meaning we only recycle about 67.2 million tons of a possible 267.8 million. Animals are also innocent victims affected by litter. Over one million animals die each year just from trash pollution alone. 60% of water pollution is also attributed to litter. At least 100,000 fish and other marine animals die from plastic pollution per year. The American society can set up many clean development systems that the citizens can follow. This will help lower the percentage of the amount of pollution. In having a good system in which the recyclables actually get recycled and disposed of properly, we can save the wildlife and our planet as a whole. Cleaning up the environment is critical, it preserves our biosphere, and helps preserve the earth's natural resources. If you don’t know what we should be recycling; we should always recycle our water bottles, newspapers, mixed paper, magazines, cardboard, plastic drink bottles, plastic product bottles, aluminum cans, and even our clothes. We should also always throw our trash away in the trash bins to keep our planet clean. Using more wind turbines and solar panels to power buildings and using more public transportation and electric trains can also reduce carbon a lot. On this earth we have to take care of eachother and put our own personal wants aside. We all can make an effort to reduce our carbon footprint and make the world a better place.

I Like this application very much you când learn to recycle and more other things???

It's not good to pollute!

One of the biggest contributors to climate change is the fossil fuels that most of us use everyday to heat our homes, power our cars, and to cook our food. This is something that is so important to fix. Something that we can do is to start using alternatives to propane gas. There are lots of alternatives out there for using propane gas, such as biodiesel, electric powered vehicles, natural gas vehicles. To heat your home there are also lots of alternatives such as geothermal power, which is very cost effective and works very well. Solar power is also another alternative to heating homes, that is so much better for the environment then gas. There are so many other solutions to heating your home in a different way, and they are not all exponentially more expensive. We should all be trying to find ways in our lives to find alternatives that will work for us for cars, heating, and all of the other appliances used in our household in our daily lives. It is hard to make an immediate switch from your old gas powered car to a new electric one, but start small. Look at how these alternative solutions will effect you and your carbon footprint. This small switch might seem like it is unnecessary and not doing a lot, but it will  impact so much if we all do our part to try and lower our carbon footprint.

Sustainable aviation fuel or SAF is a fuel made with feedstocks that can go into all commercial planes when blended with traditional jet fuel. Currently we can only blend 50% SAF with conventional jet fuel on commercial flights, but even with that limit, SAF can reduce GHG emissions by 40-47%. One negative of SAF is that it is about 3 times more expensive than conventional jet fuel. I do believe it is a necessary development if we want to save the planet.

High speed rails are an efficient cheep and good for the environment way to transport people quickly across country’s. They run completely off of Electricity and they move at around 200 mph (320 kph). The best part is they would limit the amount of people driving cars and riding on planes which are some of the biggest carbon emitting things on the earth right now. Most countries have high speed rails but if you are not in one of those countries try to bring it up with your parents or you teachers to try to bring it to there attention so hopefully we can install high speed rails in countries that don’t really have them.

if you can use less energy to move more people instead of having them drive themselfs it helps the eviroment so makes perfect sence to me

The clean development mechanism is good for the environment. The clean development mechanism is good for the environment because it causes the carbon emission in countries that need their carbon emission to go down goes down at a high rate. Another reason and way the clean development mechanism works and is good for the environment is it doesn’t always cost money(recycling cans and bottles).

For centuries we have been blessed to be part of a planet that does so much for us, yet we don't do enough for it. An example of this is air pollution. Do you know that 91 percent of the earth's population is breathing in polluted air? In the year 2017,air pollution contributed to 5 million deaths globally. A lot of pollution is a result of the gas emissions from factories. The way to reduce this problem significantly is using less factory made products.  Other ways are making home made items instead of store bought ones, or using less plastic. Another example is littering. Littering is a result of us humans leaving our trash around which ultimately affects marine life. Littering can largely be avoided if we are responsible for our own trash. This means being accountable for the garbage that you have by throwing it away.A lot of the plastic that we used ends up being dumped into the ocean and kills marine animals.A huge way to limit our plastic usage is using metal water bottles as opposed to minimal use plastic ones. My final example is wastage of water in our environment.Did you know that we waste 1.7 gallons of water annually.We can preserve about 10 gallons of water a day if we can just turn off the faucet.2/3 of the water we use comes from showers,so we should all make an effort to limit our time in there.In this earth we have to take care of eachother and put our own needs and desires aside.We all can make efforts to reduce our carbon footprint and make the world a better place.

I think I can speak for every one when I say that I want to make the world a better place. Now, don’t get me wrong when I say that. I am aware that some actually don’t want the world to be a better place; however, most of the people do actually want to make the world a better place. They are either just to lazy to or are unable to do anything about it.

I did not know that 91% of Earth’s population breathe polluted air. And 5 million deaths because of it? This is ridiculous! If the situation is this out of hand, are we even going to be able to fix it? Although using factory made products is a solution, maybe there are better alternatives. What if we convert the gas powered factories into electricity powered factories? Would that even be possible? If we are able to figure out how to make cars be powered with electricity, is it so implausible to do the same with factories? Burning fossil fuels is the issue here; factories using those fossil fuels is just something that happened.

About the littering; how exactly could we resolve that? I guess we could put out trash cans everywhere and hope that people throw their garbage into them, but that isn’t foolproof. People could still miss or deliberately throw them on the ground.

The water consumption is something much easier to fix, in my opinion. We just need to use less water. Take shorter showers. Turn off the water when brushing our teeth. Why are we leaving the water running when it isn’t necessary? What are you doing in the bathroom for so long that your taking such long showers?

As you said; we need to put our wants and desires down and put our needs first. We must make the world a better place while we still can…before it’s too late.

Supporting each other through proper housing to live in, and fresh supplies of food is important. However, doing all this can also negatively impact our environment in various ways. When more and more housing and buildings are constructed, this means more natural habitats of animals and forests will be torn down to expand our cities and towns. Many more roads and highways will have to be built as our cities expand farther away from many central parts causing cars to travel a much farther distance. For fresh food supplies that aren't grown locally to be transported from all around the world will increase the amount of greenhouse gasses being released from transportation boats, trucks, and lorries; not to mention the extra amount of refrigeration that needs to be used for the long distances. To reduce this, it's better to purchase locally-grown products as much as possible. Try taking public transit to get around more than cars, especially when the distance isn't too far.

The lack of sustainable infrastructure around Vancouver limits the "green " transportation actions that citizens can take. Although there are some parking spaces that offer electric car chargers, there are limited hydrogen car/truck refilling stations. If the city put more money into "clean" infrastructure, it would be the first step for Vancouver to have a lower impact on the earth.

them shoud recycle good and more

I think that if a large community used wind andsolar, we could reduce carbon emissions. We can convert this to hydrogen, use it to store energy, move transport and heat. Hydrogen has three time energy respect petrol! Every year we spend money using fossil fuels instead of investing in renewables.

I thoroughly agree with your viewpoint. We will gain in the long run if we invest in renewable energy, such as solar or wind power, because we will not only protect the environment, but we will also have the potential to save money. Furthermore, if everyone considered the long-term use of renewable energy, we may have a stable environment and carbon cycle.

I also agree with this perspective, implementing policies and laws that restrict the use of fossil fuels could significantly benefit the environment. This has already begun to be implemented in the law but needs to continue, for example Fossil fuel reductions in federal buildings are required by the Energy Independence and Security Act of 2007 (according to https://www.npr.org/2023/04/10/11646521 … 20levels.). If we were able to restrict the use of fossil fuels that emit harmful emissions, it would have a greater impact than individual improvement. When this becomes a requirement we will begin to see significant change.

I also agree with your stance on renewable energy. Using renewable energy instead of fossil fuels can be more efficient and better for the environment. The only drawback is that renewable energy sources usually take up more land than fossil fuel sites. However, in the long run, I believe that renewable energy will be able to stabilize the carbon cycle and ultimately help stop global warming.

I agree that wind, solar, and other forms of renewable energy are extremely important to make an impact in the fight against climate change. These solutions are some of greatest tools, because not only do they help the environment, but they can also provide jobs and other economic incentives. Personally, most of the reduction in emissions from my country, America, has been due to the implementation and usage of solar and wind!

Renewable energy is beneficial to the environment and human health. Renewable energy is also known as clean energy. Clean energy has biomass resources that cover increasing biodiversity, storing carbon in the soil, improving water quality and quantity, and controlling erosion. Renewable energy is also cheap and creates jobs. The energy is sourced from the wind, water, underground, etc. Clean energy also helps reduce carbon emissions into the atmosphere. It would create a better environment for humans and wildlife. 

https://www.un.org/en/climatechange/rai … ble-energy

here are many ways we can have a cleaner development. Starting with trying to reduce what’s been causing a species distribution (SD or SDM). If we reduce human emissions and greenhouse gases, this will cause a cleaner development. We can reduce both human emissions and greenhouse gases, by burning less fossil fuels, reducing CO2 emissions, and cleaner technologies/energy. These are some of the main advances of cleaner development. How can these have a positive impact? Will burning fossil fuels cause less air pollution going into the atmosphere as well as fewer greenhouse gases and human emissions? Reducing CO2 emissions means we will be using more low-carbon sources of energy, renewable energy sources, and renewable technologies. Cleaner technologies can lead to us using more nuclear energy and will help with cleaner and renewable energy. Not to mention how much of a positive impact renewable technologies will have on cleaner development. https://ourworldindata.org/renewable-energy is a great article about cleaner development.

Renewable energies mean a reduction in CO2 emissions and other environmental impacts, since they avoid the burning of fossil fuels and other polluting activities such as those of the nuclear cycle.
Influencing that energy sources for our domestic uses are cleaner, however, is not easy. For example, in our country there is still no electricity company that offers only "green electricity", that is, electricity from 100% renewable energy. As users we have few options to support production with clean energy, although we can know what percentage of the electricity we pay comes from renewable energy sources, what percentage from nuclear, etc. as this information should appear on the invoice. We could also inform the company of our interest in receiving electricity from renewable energies and try to create a trend.

I think that asking companies for electricity from renewable energy sources is a really good idea. If it did manage to start a trend it would lower the demand for energy from nonrenewable sources and raise demand for energy from renewable sources. This would force companies to use less nonrenewable energy sources.

Small trashes on the street can cause a big problem! When you throw trashes anywhere, you might cause garbage pollution. Garbage pollution arises when the waste collected in dumping sites keeps rotting, spreading odour and cause air pollution in the surrounding areas. (https://infinitylearn.com/surge/english … pollution/) Air pollution is affective which will damage Earth. The temperature will also increase and the ices in North and south Antarctica melts. I don’t think any one of us want that……so the best diction is to clean our environment! We can start with cleaning inside our classroom and our house. Then, we can start not to throw garbages anywhere we want to. Hope we can make it different! I hope you also read mine post!!!!!!!!!

Typo: my

I agree with you, however I think that simply disposing of waste is not the solution, and instead we should work to promote reuse and recycling. First of all, when we remove trash from classrooms and homes, we put it into garbage bins, it does not disappear when this happens. A problem that arises from this is where the trash will eventually end up, which is ultimately landfills. These landfills are terrible for the environment, and have a very negative effect on the people and communities surrounding the dump. I think a better solution is to promote reuse of trash and finding new ways to use old products. While cleaning out trash from our communities is important, I also believe it is paramount we find a way to reuse the dwindling supplies that we depend on.
Source: https://www.colorado.edu/ecenter/2021/0 … controlled.

I do agree with you but I think recycling would have a better impact. When we pick up trash off the ground we help out the environment but the trash will end up in landfills which also have a negative impact on the environment.

I think that switching to renewable energy would be better for the environment as they can help reduce carbon emissions. However, since fossil fuels are widely used, making a sudden change would not be the best idea, since many people and companies rely on them.  A gradual change would be all it would take to stop global warming. Even so, stopping global warming cannot be done with a small group of people, but the whole human population.

Cleaning and cooking are one of the biggest useful things in the world because cleaning helps with the reduce of sickness and lower the rate of having to skip work or working out.And also Cooking is a big thing because how will you eat without cooking over 90% of the world know hot too cook and it is very hepfull for the populations .

Clean cooking could reduce pollution from burning wood or coal from regular stoves and protect human health if around 43% of families would change from traditional stoves to clean cooking. Billions of people around the world cook by polluting fuels which emit plumes of smoke that cause significant health impacts and premature deaths. Actions that need to be aggressively implemented are clean cooking technologies such as liquid petroleum gas, advanced biomass stoves, stoves that heat with solar energy, ect. Clean stoves reduce greenhouse gas emissions by increasing thermal efficiency or ventilation. Unfortunately for the economy, carbon dioxide equivalent emissions can be reduced by 31.38–76.34 gigatons at a net first cost of $136.64–302.76 billion. Clean cookstoves raise cooking operating costs by $1.96–4.38 trillion over the stove lifetime because many families collect fuel for free.

When I first learned about climate change as a kid, I watched shows and documentaries from a few years ago that warned me about climate change and how if we did not take drastic action soon, our world would be forever changed. That may still be the case, but we are not too late, we can still fix this issue and come out without too much death. California’s Senate Bill 100, passed in 2018, gave me hope that the wider world was finally taking climate change seriously. If California succeeds in its goal to have 100% of its energy come from renewables by 2045, it would serve as a great example for many countries around the world with similar populations and sizes as California. If we can support more countries to make and meet goals like this, I believe this is the greatest step we can realistically take at this time to significantly reduce the negative effects of climate change.
Here is more information on the California goal:https://www.energy.ca.gov/programs-and- … by%202045.

There's quite a few ways we can keep our environment clean but some of them would be shortening how much water we use and throwing away or recycling or trash. This obviously may sound like a small step or impossible to control throughout the world but shortening like our showers by a few minutes or turning the water off while your brushing your teeth can make it a long way.

If we stop using water so long, then we will help our planet. We need to take shorter showers and with cold water, because cold showers can help save energy and warm water will use more energy.

While it is true that this is a good step we can take in the direction of stopping climate change, I believe there is much more we can do. To effectively take impactful steps to a better future, we need everyone on board, most importantly big corporations and world leaders. We need the people and corporations in power to recognize the crisis we are in, and we need to get them to make changes that will actually help us. To do this, we need to continue to fight for what we, and our world needs. I believe that the ones contributing most to climate change are the ones to blame. There should be regulations and rules to ensure a more environmentally friendly future. To truly fight climate change, everyone needs to do everything they can, from big to small.

Yes, one way of improving the environment and improving the health of people is clean cooking. Clean cooking could reduce pollution from burning wood or coal from regular stoves and protect human health if around 43% of families would change from traditional stoves to clean cooking. Billions of people around the world cook by polluting fuels which emit plumes of smoke that cause significant health impacts and premature deaths. Actions that need to be aggressively implemented are clean cooking technologies such as liquid petroleum gas, advanced biomass stoves, stoves that heat with solar energy, ect. Clean stoves reduce greenhouse gas emissions by increasing thermal efficiency or ventilation. Unfortunately for the economy, carbon dioxide equivalent emissions can be reduced by 31.38–76.34 gigatons at a net first cost of $136.64–302.76 billion. Clean cookstoves raise cooking operating costs by $1.96–4.38 trillion over the stove lifetime because many families collect fuel for free.

I will be creating a new, emission-free, clean-and-green cargo transportation ship. In order to have a low carbon output, this modern ship is going to have advanced electrical engines and renewable energy sources including solar panels and wind turbines. With zero emissions , this ship will be able to reduce pollution but also create a more eco-friendly and less carbon-heavy future for sea transportation.

It would also be extremely beneficial to use more local products/goods, even within the country since electric vehicles are so common.

The importance of corporate social responsibility is enormous, and it plays a significant role in climate change. 100 energy firms are said to be in charge of 71% of all industrial emissions, according to the Natural Resources Defense Council. Accordingly, huge corporations—especially when compared to the typical person—have the greatest influence on carbon emissions. In addition, a lot of the things utilized by the typical person that have a harmful influence on the environment are produced by corporations. The NRDC estimates that 630 metric tons of greenhouse gases are produced during the production of food and beverage firms' goods. Making and distributing these products using environmentally sustainable methods could stop this.

One thing we can do to reduce our carbon footprints is using more natural lighting than indoor lighting. Using indoor lighting uses electricity made from burning coals and fossil fuels that release carbon dioxide into the atmosphere so opening a window or lifting the blindes is a great way to let sunlight illuminate our homes that helps cut back our carbon footprints. If that's not something you'd prefer, remembering to turn off the lights before leaving and room is also a great way to help. Another thing we can do is accept hand-me-downs and thrift more often. When we buy things new, carbon dioxide is released into the atmosphere from the factories making them. This can be avoided by buying things that have already been bought and used, so more new things don't need to be made. We can thrift all sorts of things from clothing, household supplies, decorations, and more. Not everyone is able to do large things to contribute to the survival of our environment, so remembering to do little things like these in our everyday lives can help a lot.

For background information, “DAC” or Direct Air Capture system, is a product used to extract excess carbon from the atmosphere. It uses sticky receptors that the carbon dioxide sticks to without attracting any other unneeded gasses. It is able to separate a meaningful amount of carbon dioxide from the air but this process requires a huge amount of air to come in contact with the receptors because sometimes the carbon in the air can be very dilute. This process is efficient but is not cost effective and requires a lot of advanced technology to be developed and huge amounts of space. Currently, there are 18 DAC plants operating worldwide capturing about 0.01MtCO2 per year. And one plant is being developed in the United States that is projected to capture 1MtCO2. In the net zero emission by 2050 scenario DAC is projected to capture about 60MtCO2 per year by 2030. The carbon dioxide captured from the DAC systems can be implanted into the earth’s crust but more importantly, can have a second use to benefit humankind and possibly solve the climate crisis. Compressed CO2 can be used for manufacturing plastics, cement, carbon fiber, oil productions, and improving indoor agricultural yields. It can even be used for beverage carbonation which goes to show how ingrained and helpful extracted CO2 could be in the future. If we can find a way to use compressed CO2 to help with something like oil production which is already a coveted and toll taking matter on the earth to extract. It could speed up the process of cooling down the earth in an efficient amount of time to hopefully be able to save some species that are already suffering from climate change. Not only could DAC extracted carbon hopefully be able to save some endangered species but it could help humankind be more efficient with their carbon dioxide usage and help us rethink the way we produce products. Products that would normally be bad for the earth but if we use DAC extracted carbon a lot of our day to day resources could be better for the earth, which would eventually put an end to climate change.

Cleaning up the environment is critical to the survival of life on Earth. It reduces pollution, preserves our biosphere, protects endangered species, and also helps preserve the earth's natural resources

i agree, i think the first step for cleaning up the environment is eliminating plastic, that as we know it is very dangerous for animals too.
do not throw waste in the ground in the next step to breathe clean air and guarantee a better place for wildlife as well as for future generation, in small steps you can change the situation!!!

The best way to develop a clean environment is to stop the production of single use plastics. Single use plastics are incredibly bad for the environment because first of all most of them are just being thrown on the street, which is making cities look un appealing. After that, the wind picks it up and throws it into the ocean which affects sea life substantually.

I agree, if we don't clean up the environment we will have many deficiencies in our ecosystem. Fossil fuels are the leading cause of CO2 emissions. This includes transportation as well as electricity and heat. To reduce transportation emissions , we need to use less gas powered vehicles and use electrical vehicles or bicycles. To cut off gas emissions from electricity and heat is just to simply use less of it. By turning off the sink when not using it, turning off lights when not in that room, or turning off the fan when you don't need it will add up.

I agree to this idea. We have to make sure, and be responsible of our environment, and the ecosystem. It's not only where we live, buy also other hundreds and millions of other organisms. We shouldn't be selfish, and consider only about ourselves. We should think about how each and every single thing we do affect our whole environment. We are producing more and more waste each day, just for our own good. Plastics, CO2, deforestation, can all be stopped if we take our time, and help the environment. For example, get a cloth-made, recyclable bag for groceries, ride our bike/walk as much as possible, and cutting down our needs for wooden products. All are some good ways to actually do something for our environment. There are too many problems environmentally, and we should solve it step-by-step.

I had fun doing this project and learned how my actions affect the environment. It made me realize that I and others are doing things that hurt the planet every day. I want to change my habits so I can help the Earth.

How many lights stay on in schools all night? Our school is doing an energy’s audit and dealing with automatic lights which never turn off, or teachers and staff leaving lights on when the leave the room.
How can we make this as automatic as washing your hands after going to the bathroom? How can we ensure that people fall into climate healthy habits?
Are lights a very substantial factor in carbon footprints?

Clean development refers to the implementation of sustainable and environmentally friendly practices in order to reduce greenhouse gas emissions and combat climate change. To start clean development, individuals and organizations can first conduct an audit to identify areas of improvement in their daily activities, such as energy usage, transportation, and waste management. From there, they can implement changes such as using renewable energy sources, reducing single-use plastics, and promoting eco-friendly transportation options. Additionally, governments can create policies and incentives to encourage clean development practices and promote the use of renewable energy sources. By starting with small changes and making a concerted effort towards sustainable practices, we can work towards combatting climate change and creating a more sustainable future.

we can reduce the waste of water for exemple taking an short shower or taking it cold even if outside it is very cold. we need to stop wasting thing like water

I agree. I also think that there are other ways of saving water: when doing dishes or brushing teeth, turn off the water until you need to rinse. Dual-flush toilet systems, or other alternatives to flushing, are also helpful. As a society, we use excessive amounts of water - in the fortunate places - while other places are forced to travel long distances, and sometimes not even to clean water! The ocean is also becoming super polluted, so we need to stop flushing things into it. That includes sewage, plastics, fertilizers, pesticides, as well as lots of other things.

Dear people;

Our environment is very important to us and living things. Please share your thoughts about how you can SAVE OUR ENVIRONMENT.
My thoughts: We can clean up our environment. We don't use plastic. We throw trash in the trash can.

Thank you very much

Hi Clara, ok

This is a very good suggestion to do, however this is something that we could do in the short term but in the long term we could start asking are government to put in clean energy sources. Like windmills because we get a lot of wind in Canada and they could power a lot of things. The government could also put in solar panels on new houses so that they don't completely rely on fossil fuels and more on clean energy. They could also give people money to change their  cars to electric because they cost more than normal gas powered cars.

The topic of confronting climate change is a complicated task as there are many options but many politicians and ourselves included are sometimes not committed to the idea of new energy and some fossil fuel companies are actively against change. Despite the resistance of some companies, there has been much progress such as companies and countries changing from fossil fuel to renewable energy such as coal-burning countries laying off or leveling the amount of coal used(Chart of coal usage in countries*). Since countries are laying off on fossil energy, we should also use solar panels and wind energy to help lower the amount of fossil fuel used and use cleaner energy appliances such as electric cars and LED lights. We could also create an organization that mostly concentrates on more renewable and cleaner energy sources and band all countries to petition and support these ideas.
*https://www.bp.com/en/global/corporate/energy-economics/statistical-review-of-world-energy.html

I definitely agree! Creating an organization that concentrates on renewable energy is definitely a good alternative to fossil fuel usage.

I believe that the countries in the world who want to improve pollution and reduce climate change should come together to band an organization promising to eliminate things like gas-powered machines by 2050. With more resources, it would be easier to implement electric powered machines in multiple countries at a time. In this organization, the companies could lend each other money in order to start organizations that help reduce climate change. The Millennium Development Goals are quite unrealistic and with only one country it would take decades

I have seen a lot of news about new technology that can improve transportation, but most of them are not much better than existing technology that we just aren't using. Los Angeles had a very good electric street car system in 1895 that was probably better than what some cities have today. The only thing stopping us from having efficient transportation everywhere is corporate lobbying and political opposition. Trains and streetcars have existed for over 100 years and there is no reason why any city should not have them.

When people think of carbon neutral energy sources, renewables come to mind, however renewables have downsides that a lot of people do not acknowledge. Solar and Wind energy are often seen as the quintessential renewable energy sources, however most do not acknowledge that solar panels only last for 25 years under optimal conditions (which could be severely shortened by storms and natural disaster), and after they break, it's likely they are not disposed of properly and the heavy metals they contain seep into the environment. Furthermore, Wind farms are very obstructive and pose a major hazard to birds, and can also be destroyed by storms. They also do not provide enough energy for entire cities, and all of these problems can be circumvented by nuclear energy. Nuclear reactors only cause a tiny amount of carbon emissions, but in exchange they provide an unparalleled level of energy. Through the use of Thorium, nuclear reactors eliminate the danger of a major meltdown, and thorium cannot be used in nuclear weapons, which are the two biggest concerns about nuclear. I think a greater emphasis needs to be placed on nuclear energy, since a lot of nuclear reactors were built several decades ago and modern technology could massively improve the efficency of nuclear reactors. Nuclear could be a long term solution to replace fossil fuels, which is a feat renewables likely cannot achieve due to the inconsistency seen in their energy, as solar and wind both heavily depend on the weather and climate to be functional, whereas nuclear would provide a constant stream of energy.

We can help keep the planet from further warming through reduction of water use/waste. For example, taking shorter showers can save gallons of water and taking cold showers can help save energy. Taking hotter showers needs more energy use and increases gas emissions.

I believe that it would be possible if everyone in the world made it their top priority. However, with all of the countries competing for resources and money, it would be difficult to come together and agree on how to get things done. Additionally, governments put large amounts of funding into other fields, like military. It would only be possible to complete so much in 2 years if our entire political structure changed.

We should stop using coal or gas generated electricity. Like in Germany, many houses have solar panels to not use coal and gas generated electricity.

I think one of the problems with solar and wind power is that its only available when its windy or sunny. This is what causes it to not make complete economic sense. However if we could develop a system of giant batteries that could be used as power banks so we could have a storage of power and electricity for when its not windy or sunny. This would make it possible to rely on just wind and solar power and completely cut out fossil fuels

I totally agree with you, it's a great idea to store the electricity producted by a solar or wind system in batteries.

*In addition to this, where I live, the weather is particularly sunny and windy therefore we can collect quite a few electricity. Unfortunately we can't store it.

You dont need 20-30 mins for a shower bestie

I do agree with you. I think people should use cold water instead of hot water, it avoids high electric consumptions and it allows people to bathe in less than 5 mins since it's cold hahaha

I've definitely seen it mentioned in this forum, but electric cars are currently a great option for reducing one's personal carbon footprint. However, currently, there are very few electric vehicle chargers that exist throughout cities. The ones that do exist are usually concentrated in more affluent neighborhoods, meaning that their ease of access is very low for the average person. In the future, we need developments that will promote sustainable lifestyles, such as more electric vehicle chargers sprinkled throughout a city so that people can feel motivated to buy an electric vehicle without the thought nagging in the back of their mind about the annoyances that come along with a sustainable car.

I agree, electric cars are better for the environment and I'm glad to see it making a bigger change on earth. But, it is very unaccessable to the average person. I feel like companies should focus more on electric cars and making them cheaper for the average person to invest in

I agree I feel like Teslas are the most popular electric vehicle and it's what most people think of when you hear electric car and since they are so expensive many people think the idea of an electric car is out of the question. And that goes along with what Sylvan said about placement of EV chargers, you see chargers in neighborhoods where people can afford electric cars which is part of the problem. There are other companies that make electric vehicles for cheaper but they are still most common in bigger cities where more chargers are available. If electric vehicles were more accessible they would have a bigger impact on the environment.

The main problem I see with a Tesla is the charging port. This isn't only a drawback of Teslas but electric cars and manufacturers in general. What we need to do is have a common charger that every car uses, kind of similar to iPhone vs Android. The network would be much denser if we only had one type of charger. That being said adapters do exist and I am aware that Teslas come with a J1772 adapter which is the most common charging port in electric vehicles. It would just be nice if we didn't have to horse around with adapters and could just pull up anywhere and charge without even having that thought.

In the short term, electric cars might seem like the option to go, but overall, the manufacturing process and materials required are much less enviromentally friendly. Most electric cars use a Lithium Ion battery, which is made by taking away water from ponds, rivers, having it to evaporate in the sun, to concentrate the necessary material's in the soil to create the battery. Meaning that creating the batteries essentially destroys natural animal's habitats. In addition, because of the complexity of an electric car, the Union of Concerned Scientist (USC) have found that the carbon footprint of producing an electric car is around 15-68% higher than producing a normal car. In addition, an electric car must be specially recycled to prevent harm to the enviroment, so as the popularity of electric cars increases, I believe recycling and disposing of cars will become a problem in the future. Finally, the average electric car has an average of 3 miles per kWh. Around 60% of electricity is created by fossil fuels, this mean that a electric car actually consumes more fossil fuels than a normal petro engine car. The concepts of an electric car is really smart and theoretically a lot more enviromentally friendly, but we still have a long way to go before this can happen, we definetly need to put more resources in research better ways to create and sustain electrically vechicals.

One thing is more electric cars to reduce the amount of gas and petrol used. Another using more wind turbines and solar panels to power more buildings. Also using more public transportation and electric trains would also reduce carbon a lot.

The higher use of public transportation and electric trains would also increase the flow of traffic since there would be less people on the roads and more people in the trains or other types of transportation.

Population growth is a major problem for the environment, and one that continues to grow. For most of human history our population size was relatively stable, until globalization during the 1950s, when innovation and industrialization, energy, food, water, medical care, and other resources became more available and reliable, causing a surplus. Consequently, the global human population rapidly increased, and continues to do so, with dramatic impacts on global climate and ecosystems. The world population is growing rapidly, far outpacing the ability of our planet to support it. Overpopulation is associated with negative environmental and economic outcomes ranging from the impacts of over-farming, deforestation, and water pollution to global warming. As the population grows and the demand for resources to support it grows as well, negative environmental impacts from production and burning fossil fuels increase enormously, contributing to individual carbon footprints as well as global emissions. This is a very big problem, but not one with a simple solution, so we need to look at ways to decrease carbon emissions but still support the growing population.

As of recently scientists in India and around the world have been finding new and improved ways to try and make more products such as shopping bags, straws, and plastic bags biodegradable.
     Everyone knows about the increasing problem with sea turtles and other ocean life getting plastic straws stuck in their noses as well as intestines. While in some cases, issues like this aren't fatal because the animal gets help or the straw gets unstuck itself naturally, that's not always the case. Often complications such as the ones mentioned aren't only extremally painful but can prove to be fatal for the animal and its environment. However, more and more companies are trying to implement new sustainable practices to cut down on the number of straws they use. https://money.com/starbucks-hyatt-ban-plastic-straws/ For example, more restaurants have quit offering straws all together or they offer paper alternatives. While this is more common for beach front establishments, important companies such as Starbucks, American Airlines, and Disney have claimed that they will be banning the use of plastic straws within the foreseeable future.
     The problem with normal plastic bags is that they can travel extremally far and on top of that, look very similar to sea creatures. Jellyfish predators such as Sea Turtles, Sun fish, and Tuna fish end up mistaking plastic bags for their main food source. As if that wasn’t bad enough, plastic bags have been seen stuck on coral reefs and along the ocean floor. When these plastic bags get stuck on coral, they choke it out and cause it to die back, resulting in habitat loss and destruction. When plastic bags get stuck on the sea floor it can prevent some ocean species from burrowing and making dens in the sea sand, which, also in turn results in habitat loss and destruction. Not only are big name companies banning the use of plastic straws but, scientists have developed a substance very similar to the plastic used for making shopping bags that completely dissolves in water. https://www.youtube.com/watch?v=oqE20TFl6cY These bags were originally designed to aid India in its plastic reduction, but environmental advocates are pushing for companies all around the world to adopt this much better alternative.
     Plastic utensils are dangerous to both humans and animals in a variety of ways. When plastic cutlery breaks, it sprays out micro pieces of plastic that dietary tracks can have difficulty processing and, in extreme cases, can cause bleeding. The same thing happens to animals like sea lions and dolphins that chew up plastic and cause it to break and splinter into bigger pieces that get lodged into their throat and stuck in their stomachs. To even further reduce plastic waste Bakeys, a company based in India, has created edible and durable utensils. https://www.kickstarter.com/projects/12 … y-utensils  Their products don’t dissolve very easily in liquids and are made from rice, wheat, and sorghum flour. On top of that, the utensils have a shelf life of three years and don’t contain any preservatives. The company’s goals are to eventually eliminate the need for plastic utensils around the world.
     While the environment and the world are suffering from human impact and pollution, all hope is not lost. People are trying to correct mistakes and live more sustainably and on top of that, provide ways for the common consumer to lessen their environmental impact through small and attainable steps.

Great post!

Add tras can to rivers for plastic, glass and paper

This is a little bit bigger than a trash can, but trash collecting devices have been implemented in a few places! My favorite is Mr. Trash Wheel in Baltimore, Maryland, USA. There are four of them in the harbor there and two more planning to be installed in California, USA and Panama. Currently, the trash collected is being burned for electricity.

The Earth needs to stay clean. There is so much pollution going on now a day that nobody is willing to even care about a cigarette bud on the ground. What most people do not think about is the consequences that are included in every pollution that happens daily. It is sad to see the disrespect that most Americans show to the Earth and then the care that is not given to the Earth.

The American society can set up many clean development systems which the citizens can follow that will help lower the percentage of the amount pollution. In having a good system in which the recycles actually get recycled and then the trash gets disposed of properly. If the mindset of the people in this country changed to them caring about the planet and caring about the future and the Earth, then there would not be such a big problem in the clean development of Earth. Just a simple change in the mindset of people to think about pollution before actually polluting would help out this world tremendously.

Finally, having a good system that will help the pollution in this country and around the world will help all different ecosystems and will benefit the health of this Earth.

We should always recycle our water bottles, newspapers, mixed paper, magazines, cardboard, paperboard, plastic drink bottles, plastic product bottles, aluminum cans, even our clothes. And we should never litter and always throw our trash away in the trash bins to keep our planet clean.

i agree  we should recycle  )

If we do somethings at home by hand or use electric tools (if possible for you) we can reduce the carbon footprint a lot. Even if we reduce the footprint of what we did at home by a quarter, that would be almost 1000 kgs (2204 pounds) which would leave the average usage around the world to about 8800 kgs per capita.

Littering can lead to an unhealthy environment. When we litter, we are dirtying up our planet and affect other communities around us. Also, a lot of this plastic waste we litter can be consumed by animals because they think it is food. This causes them to die and maybe have a huge decrease in their population. Let's keep our planet healthy.

For years now the word has relied on gas and oil fuel vehicles to bring us transport. Little do people know or care hoe this could be affecting them. The after product of running gas through your car is green house gases and to many green house gases can cause for to little sunlight to get through to earth. We also breath in these toxic fumes damaging or lungs and body.

One of the major contributors to carbon emission is the vehicles we travel around with. Vehicles that use gasoline for fuel releases tons of Co2 into the atmosphere every year. Coming from a MEDCs like Vietnam, our streets are filled with motorbikes and cars that only use gasoline. I know the same applies to many other countries as well. That is why I believe now is the time for the transition of using other eco-friendly alternatives such as electric or vegetable oil. Electric can easily be generated from renewable energy resources from wind farms, solar panels, and tidal power. We have already seen a first glance at the success that electric cars could bring from their recent use in the U.S. Without a doubt, a reformation to sustainable fuel will help us reduce our carbon emissions significantly.

Hi, I agree that cars that use oil are playing a huge part in pollution. Hybrid and electric vehicles can help save our environment by limiting the amount of carbon dioxide that get released into the atmosphere. Converting all the cars from oil to electric would be very difficult and most likely wouldn't happen until the far future, but each conversion would help the environment bit by bit.

I, personally don’t own an Electric Vehicle, but I understand people’s reasoning of owning an electric vehicle. I competed in a competition in which the main goal was to explain the differences between electric vehicles and and gasoline vehicles. I believe that Electric Vehicles are superior in terms of them not emitting as much co2, but they still emit some co2. Opinions below?

I agree, electric powered vehicles don't need motor oil changes and while that still emits some CO2, it is much lower than the emissions from a gas powered vehicle. Because they have not tailpipe, pure electric cars can produce little to no carbon dioxide while driving. Although the production of an electric car tends to be have a higher emission than that of a conventional car, in the long run the carbon emissions of an electric car tends are around 17-30% lower.

In general, I do agree with the fact that electric vehicles are considered to be less environmentally impactful than gasoline vehicles. However, electric vehicles can also cause huge detrimental impacts on the environment. For instance, the magnets found in permanent magnet motors contain rare earth metals in which the mining process requires much energy and can release toxic compounds. Moreover, electric vehicles aren't truly zero emissions in many cases. This is because some electricity provided to electric vehicles comes from the burning of fossil fuels in a distant power plant making their pollution much higher than gasoline vehicles. But, overall, if advanced technology used in the future can solve these related issues, electric vehicles will be much better for the environment than gasoline vehicles.

I think to reduce greenhouse gas emissions we need to have more clean development solutions. An example of this could be to use products that can be recycled to reduce pollution which would help have better clean development. Another example could be to use electric cars to also reduce the amount of pollution on the Earth. Electric cars instead of cars that use gasoline could also help improve clean development on the Earth. A third solution for helping Clean Development could be to travel better and using less energy. Traveling better could be carpooling or taking public transportation or using a bicycle instead of a car.

I do like your point about having more electric cars because of their lesser effect on the environment but I don't think that is a good long-term solution. The process of mining the Lithium required to make car batteries is extremely harmful to the environment and then transporting it to the assembly plant is another way the process creates pollution. I think if we can find a way to recycle the batteries better and reuse them the whole idea would be a lot more effective. I think the most effective thing that you mention would be taking public transportation or carpooling.

To improve and change the world we have to recycle and help the world for example when you rinse you turn off the water so we don't waste it, or when we brush our teeth you stop the water until you need it.

Well done, I like your idea

thats a very good idea i do that in my house

The truth is that I think exactly the same and not only the water but to recycle the products or another very good idea would be instead of using the car so much if you have to move around the city or town use the bicycle and if it is in your own town walking, a personal comment of mine is that, for example, if I have to move around town, I take my electric skateboard, which pollutes less.

I think that all the people must to do in their house.Well done

Hi Javi, I like your ideas, if everyone did the same or followed these tips or other similar ones, the levels of contamination would decrease.

Yes, I agree completly. I am at fault for wasting water when brushing my teeth, and I myself need to imporve. I appreciate you spreading this message, as every little thing helps, and your voice has changed my sets of thoughts.

I completely agree. Those small actions can all add up and help the environment much more than you think.

Yes, Mr. Javier I wholeheartedly agree with your stance on how the environment can be improved, we do need to turn off the water when we are brushing our teeth because wasting water is not good. I will now pay attention to when I have the water on when I am brushing my teeth and kick myself if I do. Thank you for sharing

I strongly agree with your claim, recycling is probably one of the easiest accessible things for us to do to help the environment.

I definitely agree with this post! Recycling our plastic will prevent them ending up in our landfills, killing our marine life, and polluting our water. These small changes in our daily lives, like turning off running water and recycling, will certainly improve and change our world in a positive manner.

I agree. Just small things like turning off the faucet when you brush your teeth may seem insignificant, but over time they add up and will definitely go a long way in ending this problem.

I agree. Even though it seems like a small thing. If everyone does this small thing that that becomes a big thing and helps the environment a lot. Turn off the water until you need it(it does make a difference)!

Hi Javier,
I also agree with your statements. I also think that recycling is a major way to have better clean development on the Earth. Turning off the water when doing things like brushing your teeth is also a good idea because it is an easy way to improve the environment. Another way to have more clean development could be to use more efficient transportation.

I think that an important aspect of lowering carbon emissions is finding a way of clean development. Countries like Nigeria, Niger, and other countries that are in the process of developing need a way to cleanly develop without carbon emissions; Considering the sheer amount of people that they have not being fully developed, a fully developed Nigeria would require tons of carbon emissions to built facilities for all the people that a fully developed Nigeria would have. If nothing is done about clean development then it would lead to an ever larger carbon emission because this second wave of development would dwarf the old development of the United States, United Kingdom, Germany, and other long developed countries.

In my opinion, there are many effects to having a huge amount of carbon footprint but,four of the effects that have a huge impacts with humans is people that smoke, using to much plastic when we can reduce the amount of plastic that we use, water, and energy. Water is a major effect when it can effect our life at any time like wasting water or taking to much time showering. This can effect us by having a water shortage and not having water when we need it.

We all should stop using plastic bags as well as non reusable plastic and instead use something that will break down in the nature

This is very agreeable. I see plastic bags everywhere on the street and it pains me that people don't pick up or reuse what they get. This shows that we don't care what we do, just to make our lives easier. The plastic bags that can break-down are a good substitute for normal bags and even if they aren't better, they're better for the environment. This could solve a lot of trash problems that are currently in the ocean.

I agree with this as well, there is no reason other than accessibility why plastic bags and non-reusable plastic should be continued to be used and just left in our environment to harm others. With our modern production capabilities, many substitutes, that are just as good if not better, have been made using way less harmful chemicals and other things that continue to harm our environment.

In my opinion to have a clean development we don't smoke, we reduce the consume of plastic, water and energy.

I agree with you, but I also think that we can do a lot more than that to develop a clean environment. We could use alternative energy to produce products, try to make cheaper and more electric cars, and maybe even ban the use of fossil fuel. The last one is really extreme but I think that if we could do that one day, then the amount of fossil fuel in the air would go away.

I agree with your last statement Trevor, about the banning of fossil fuels. We have other forms of producing energy that may not give us as much as fossil fuels, but are definitely sustainable and are actually better for our earth. Things like Hydroelectric, Harnessing the wind, also maybe even nuclear energy.

Yes, I agree that we do need to stop wasting preciosus resources. Our planet is already strugling to support 7 billion people,and to support more we need to be more consevative.

Yes, I agree, but, I think that this will be hard to do immediately.  Many people are addicted to smoking, and will not change their ways so easily.  And, it will also be hard to convince others to limit their plastic, water, and energy use, because it doesn't technically affect them personally.

I also agree with your last statement, as well. Things such as reduce the amount of materials we use everyday is an easy fix, but for those that are addicted to things such as smoking,you will need some heavy convincing if you wanted worldwide change in smoking habits.

I agree, we should save our resources. Even though stopping old habits is hard, we should do so for our environment.

We all have our wants and needs but, some don't realize that they are harming our environment while doing it. Things like driving, electricity, even cows are contributing to our carbon footprint as a society. We need to use more of the renewable resources that are available at the moment. The problem is that some people can't afford to switch their entire lifestyle to use more renewable resources like using solar panels. To some people, solar panels are a good investment to others they are too expensive. Renewable resources need to be made more accessible to all.

The simple answer is: go electric, save the polar bears. The long answer with evidence and things would be: Everybody should do their part to help prevent the greenhouse gas effect and reduce climate change, and an easy way to do this for the upcoming generation is to purchase electric cars. Cars that use gas for fuel produce exhaust, which contains many greenhouse gases such as carbon dioxide and water vapor. These type of cars put these greenhouse gases into the air, quickening climate change. It shouldn’t be that hard to find a local electric car dealer near you

I have done some research, and realized that even though electric cars directly don't produce any emissions, the production of electric car batteries and the amount of electricity they use is detrimental to the environment as well. The car itself may not be producing carbon dioxide, but the factories that produce the cars still produce a large amount of greenhouse gases and the materials needed for those cars still require a lot of not recyclable materials. Therefore, cars in general are harmful either way. We should instead use bicycles and walk as much as we can, because they are not as harmful.

Since my family owns electric cars, I thought the same as you before. But after further research, I realized I was wrong.

Carpooling is widely regarded as a good way to cut down on your carbon footprint. Many people in my area do it as it is not only convenient but also saves your family money on gas. However, very few people carpool just for environmental purposes. Overall, carpooling is very beneficial with very few downsides. Carpooling whenever possible is always the better option.

Energy use from unused lights and appliances is very high. Cutting down on energy use, or switching to clean energy sources can help decrease your carbon footprint. Leaving devices plugged in when they are fully charged also takes up a large amount of energy. Unplugging devices when fully charged decreases energy use, and can also help decrease your carbon footprint.

Travelling by plane takes a lot of fuel, and has a much larger effect on the environment that driving or taking public transport. When possible, limit travel to a reasonable level, and try to take energy and fuel efficient vehicles.

Take smaller shower. Use less water. Might be more stinky but you save the earth little stinky people. Using less water means more water for fish. Fish are better then humans anyways, so use less water.

Transportation is a big contributor to CO2 emissions but there aren't many eco-friendly alternatives available. Electric cars for example are very expensive which means most of the public doesn't have access to them. If there were easier or cheaper ways to make electric vehicles they would be able to be sold for cheaper and this could lead to a significant decrease in the amount of pollutants cars emit.

I agree. I think that electric cars should be cheaper. In the next decade if the prices don't lower I think we should go to the city or government and protest. All they want is their money, but they don't think about others and that the world is struggling and it's getting worse. We need to take action before this gets out of our hands.

I agree with your statement. Transportation is a huge contributor to CO2 emissions and electric cars should be way cheaper. In the upcoming years, if car companies, don't decrease the prices of electric cars, we should all come together and protest against the government. The general public needs electric cars if we want to significantly decrease the levels of CO2 emissions.

I 100% agree with your statement. Electric cars for now are selling at a really high price, but for an alternative you can ride a bike or use a bus if possible. Even though buses commit CO2 it's much more eco friendly than cars because buses carries tons of people at a time unlike cars which only carries a certain amount of people. It's only a matter of time before more companies starts making electric cars. Planes on the other hand does not have an alternative. maybe in the future they could make a eco friendly plane.

Nuclear-powered energy plants have been around for decades. The vapor-spewing towers are an unmistakable trademark of clean nuclear power. But what makes these reactors environmentally clean? It's because the nuclear reactors aren't burning anything to generate power, they are utilizing the heat created by radioactive substances. This means no direct emissions from the fuel. The only things coming out of these reactors are water vapor because water is used to cool and control the temperature of the reactors and in many cases, the water vapor that is made is also used to create additional electricity by moving turbines that are built into the chimneys of the reactor. After all those positives, it's no wonder nuclear power accounts for a fifth of America's power every year. But there some cons to the radioactive workhorses of the west. Nuclear reactors are very high maintenance and human error can lead to the meltdown of a plant, rendering the surrounding area inhospitable. Thankfully there are many modern measures in place that make the reactors of today extremely safe and the risk of a meltdown is practically 0. Though real problems arise after the nuclear plant runs its course when the radioactive material is spent. The nuclear waste that is left is extremely hard to dispose of safely. You cant bury it, and you cant dump it, so what happens to the radioactive waste? It is actually stored in select remote facilities, where it will sit until we find a real way to use or truly dispose of the toxic contents. That is a very basic rundown of how nuclear reactors work and their place in the world.

Looking at my footprint I think I need to do better and start thinking of the world and the environmental issues because the change in myself starts with me. Looking back at my home score I see that the home score is the highest score of them all and I feel as people and myself have this mindset of just taking the easy way out of home appliances and not thinking about how the "easy way out" is harming the earth. This has helped me learn that I need to start thinking about how I can make a small change in the earth and using apllince that does not hurt the earth.

From 1990 to 2016 we have lost 502,000 square miles from deforestation. All those trees that were cut down would have taken in carbon dioxide, through photosynthesis which would have slowed down the affects of climate change. One way to help reduce he amount of trees were cutting down or at least help the he forests recover from our massive deforestation would be to plant a tree for every tree we cut or use less paper products so there would less of a demand for paper products and so the rate of deforestation would  decrease.

I agree with what you're saying, but we have to keep in mind that trees can be cut down at a faster rate than planting them, especially since it takes time and extensive care for trees to regrow at their expected height. What would be more worthwhile is to have stricter regulations on cutting down trees and have zones where people are and are not allowed to deforest, so that saplings can be planted and taken care of.

While I certainly agree that reforestation is essential to contributing to global cooling and carbon sequestration, I agree with Johanness that the process of erecting trees is quite slow and that regulations would likely be much more effective. I also think that making urban sprawls sustainable and integrated into the ecosystems which they supplanted will expand the acreage for reforestation.

I certainly agree, and I think we can take it a step further by planting 2 trees for every tree we cut down, since we lost a considerable amount of trees to forest fires and deforestation in just the past 2 years.

I also agree that deforestation is a huge factor in climate change, as the carbon dioxide in our atmosphere grows we are also cutting down the trees that could help filter it into oxygen. Deforestation definitely needs to be regulated, and reforestation is essential as well. However cutting down our use of paper products can be difficult. Often paper is used as a substitute for plastic which also harms the environment and people might go back to using plastic if paper use was cut down. If we could find an alternative to both it would greatly help our goal of stopping climate change.

Hi there, Jesse! I agree with you on the fact that we should cut fewer trees since forests (especially rainforests) are the lungs of our planet. But I don't really see the problem with using paper products. I think paper should replace plastic as much as possible while still maintaining that natural balance and planting more trees. And at the same time, we could create products using sources of other vegetation, such as algae and other quick decomposing substances from the nature.

In January of 2021 congress passed a two year extension of the solar energy investment tax credit. The impact of this extension is expected to be in the range of $1B to the solar energy industry. The ITC extension is applicable to utility scale markets as well as commercial and residential installations. The Solar Energy Industries Association (SEIA) and the American Clean Power Association (ACP) were key influencers of this legislation.

The extension of the ITC will affect not only jobs and the economy, but have a significant environmental impact. Based on the estimated amount of additional solar installations, a key environmental benefit will be the offset of 100 million metric tons of CO2 emissions. In additional the solar industry could generate enough electricity to power 19 million homes.

Universal education is still a big issue in today's world. It is best to focus on education in rural and poorer areas, especially those with poor or no education at all. We can also build schools in the most environmentally friendly ways. It is also best to train more and more teachers and professors for the future ahead with more schools and educational facilities.

I completely agree that universal education is huge, by providing education to poorer districts it an help level the playing field and provide equal opportunities to everyone. Building schools in environmentally/sustainable ways is super important to. My school uses wind and solar technology to provide energy in a clean way which could be used in other schools too.

That’s true. By building environmentally friendly schools and making them open to everyone we can teach more people about carbon footprint and how to lower it to help the environment. Especially for poorer districts.

Yes I totally agree. The school districts have to start investing in making their facilities greener. My school district passed an agreement to cut all fossil fuels used in the Seattle public school system by 2040 which is pretty cool and I hope other districts do the same. I also agree that we need to have universal education for everyone as well as education on green energy to teachers and students and all new schools built should be fossil fuel free from the start.

While I agree that having greener schools and making sure education is accessible is important, I feel like one of the reasons that some people can't go to school is because the schools they live near are over capacity.  It's hard to fix that problem without making a bunch of new schools closer to a bunch of different types of neighborhoods, not just upper and middle class ones.

Although gender equality has improved greatly, poverty and hunger are still a huge issue especially with the global pandemic. Poverty has increased greatly, ¨Nation's poverty rate has risen at the fastest pace ever this year after aid for the unemployed declined. The U.S. poverty rate has surged over the past five months, with 7.8 million Americans falling into poverty¨(https://www.washingtonpost.com/business/2020/12/16/poverty-rising/) With the stimulus check around the corner, this might help many american´s back into homes and for families to be able to feed their own families. But some people won´t be able to qualify or be legally capable of getting that check meaning a lot of families will be suffering until they are can get some sort of job.

You make some great points about how many people are struggling especially with the global pandemic happening.  However, do you think we can help people climb out of poverty without making the climate crisis worse?  I think it's possible but only if green or renewable energy companies are willing to give up on some of their profits.  Or even when it comes to food based companies.  I know we have to eat less meat and more organics but eating healthier is often more expensive.  These options are not so easy for families who are just getting by.

I agree too. I hope we as fortunate people open our hearts to support especially in need. If you are looking at my post and you haven't donated at all in your life, take action now.

Having three trashcans for recycling, trash, and compost is very important. Throughout the year I can't imagine how much useful material is thrown into the trash & ends up in a landfill. Although some places around the country implement this, it does not get as much attention as it should. We can replenish & save our soil by reusing products.

This is very true. Having even more bins for sorting plastics into #1s, #2s, and #3-7s makes going to the dump easier. Sorting into boxboard and mixed paper, newspaper and magazines, and cans can streamline the process and make less work for the sorters at the dump. Commercial composting is growing in my area, which is good for people who either don't want to compost or don't have the space. For people who do have the space, composting is a great way to get rid of food scraps.

This idea can be very effective if public figures can enforce and present it enough. My family tries our best to sort out all of our plastics into the correctly numbered bins, and also participates in a local composting organization. It’s easy to get into the habit of recycling and composting, so I think if enough influential people can spread the word about it, the idea could spark into a very effective and widely-used way to reduce carbon emissions.

One way not to pollute when the garbage can bag is full is to take a cloth bag and throw things into each container and at the same time that you don't throw away so many plastic bags you recycle and contribute your grain of sand, come on, we can all.

I think that it is often taught that going vegan or vegetarian is the only way to eat sustainably or make an impact but there are also other ways. Purchasing meat or dairy products that are sustainably raised is also better for the environment. Supporting farms that are free range or have better conditions for the animals os also better ethically. Switching out meat for a meat substitute or milk for a nut milk even just once a week can have a positive impact.

I agree that being vegan is not the only way to eat sustainable because even reducing the amount of meet or animal products would help the environmental a lot. Its is a shame though that the price alone is what turns people from eating buying free range meats and organic foods.

I agree that even making the smallest change can play affect to the larger environmental problem. While people do not have to change to an extremity, making small changes to resort to more sustinable options is also beneficial.

I agree that there are lots of steps to take even if you don’t stop eating meat all together. Such as cutting out certain meats that have the biggest impact, such as beef. But then still consuming chicken, pork, turkey, etc. of which that come from sustainable farms. Also, eating locally can lessen the transport it takes to get a food item from place to place.

I agree there are many ways to sustainably eat. Trying to not eat as much meat is a great way but there are others. For example, sourcing your food locally can reduce the carbon footprint of say a peach form Georgia traveling to Maine. You can also support local farmers markets, by doing so you are supporting small business while buying food responsibly for the environment. Personally I try not to eat much meat because I know it is a small way I can help the environment in my everyday life.

Recently the "trend" of thrifting is very popular which is great because it helps keep clothes out of landfill and our oceans. THrifting is a easy way to try different styles because even if you don't like it you don't feel bad for cutting it up or painting it to something you do like.  Stores like Hollister, American Eagle, H&M, Urban Outfitters and other store need to start a way to recycle their used clothes. I mentioned these stores because these are the most popular with teens like us or Gen Z. If we can find a way to recycle our clothes by not just donating the clothes it might be a bit cheaper. Other than that there are fashion designers who have started using recycled material to make clothes but they are not as widespread as I hoped it is. Are ability to reuse and recycle clothes is the best way to show teens that they can make an easy change and be able to express themselves.

I would agree on the "trend" of thrifting is great for the environment and that are the ability to reuse and recycle clothes is an amazing way to show young people in this generation to make a great change to help the environment but also express themselves at the same time. Personally, as a person in my youth, I would say people my age like buying a lot of clothes because that's how we express ourselves and we are experimenting with fashion too so thrifting is a great way to save money too. Also, some young people like to tie-dye and be creative with art in their fashion so I hope to see thrifting as a more common way of shopping and not just a "trend".

I also posted on the same topic of regarding fast fashion and how thrifting can be a sustainable alternative. Your connection to these popular brands such as H&M and Urban Outfitters to specific generations come to show how the younger generations can make changes for their futures. I agree on the idea to reuse and recycle clothing and fashion items and how thifting is a sustinable trend that people can catch on.

The practice of thrifting has been going on for a while, personally since I was a baby. Im glad we are starting to practice thrifting as a society. It helps the environment to recycle clothes, also helps to stop child labor from big businesses like urban outfitters and h&m

I totally agree that thrifting is a great thing and it is definitely getting popular which is awesome this definitely will help eliminate some of the waste that comes from clothing and throwing it away. It also helps with the chemical pollution that making cloths causes and the amount of water. Cotton takes a lot of water to grow and is liked by pests so the people that grow cotton will use chemicals to keep the pests off of the cotton which then this causes soil acidification.

I’ve been shopping at thrift stores for a long time. It’s great for the environment by keeping clothes out of things like the ocean, and you can find some really nice things for a cheap price. I recommend thrifting to anyone who wants some new clothes to wear or who wants to experience with different styles.

I agree thrifting is a great way of keeping clothes out of landfills and a way to not support fast fashion. The mass production of clothing is a real problem and thrifting is a something one can do if they want to help sustain a healthy environment.

Thrifting is a great way to get the clothes that you want for half the price and is much better for the environment then buying new. Not only does it help waste in the ocean, it also gives you unique clothing, its very likely that no one else will have this item. So its great that thrifting is popular even more so for the environmental side.

Landfills are a huge issue this nation is facing concerning soil and air quality deterioration around those areas. In most cases, the soil the landfills are on are near permanently unusable. Studies showed that in California alone, nearly 40 million tons of waste was thrown in a landfill in 2018, 99% of it still in California and the other 1% exported out of the country. A way to mitigate this is to recycle anything recyclable, compost as much as you can and to find a way to reuse any materials that aren't damaged or lightly used as to mitigate the amount of waste going to our landfills.

I completely agree with your ideas of recycling, composting, and reusing. I would also like to add the idea of using waste as an energy source I believe I heard about that somewhere and it is supposed to be a lot better for the environment.

I agree that landfills are horrible answers to our trash problem. I think as well as introducing more recycling and composting into our world, we also need to find a way to diminish the creation of that trash in the first place. For example, creating better food packaging and item packaging to be more sustainable. Maybe created out of something compostable like rice paper or vegetable starches.

We can all try to cut down on waste we create, making less trash that ends up in landfills each year.

Yes I agree with this. I have a couple ideas on how to do so. First off we can all (if access to it) use laptops, computers, phones,etc to take notes on instead of paper sheets in order to prevent use of papers at school. Also to stop using grocery plastic bags at stores. Instead use reusable bags or even no bags at all. Lastly something small would be to just throw stuff in the recycling bin when done with it:)

I agree with both KG1StanleyJ and tompaul04 and I would also like to add the idea of benefits for those with little to no waste in trash cans each week and only use the recycle and compost bins.

Poverty and hunger is a big issue in today's society. With climate change on the rise, it is best to know what is equitable for all. My idea is to pass legislation requiring the government to give all necessary supplies needed to survive and those especially needed to combat climate change.

The methods we use for farming worldwide is causing mass erosion of soil. It is also polluting our rivers and lakes, as well as causing "dead zones" in the Gulf of Mexico. Some solutions to this is to use less fertilizers or perhaps switch to more sustainable methods of farming, such as no till.

I completely agree. We could also decrease water usage and pollution by using more efficient irrigation tactics like drip irrigation.

While the circumstances are different in the current time of pandemic, making changes how we use transportation can play a huge role in reducing our greenhouse gas emissions. In the case outside of the pandemic, we can resort to walking, carpooling, taking public transportation, biking, etc., as ways to reduce both carbon emissions and traffic congestion. For those willing to make a greater longterm change, purchasing an electric vehicle is a great way to reduce ecological damage.

I totally agree with your take on promoting carbon-efficient forms of transport. That was a major focus of my initial post, as I was quite shocked as to how much carbon I emitted just from getting from place to place. I believe that electric public transportation infrastructure is the way of a sustainable future for sure.

I agree as well! These are excellent practices to reduce one's carbon footprint. The pandemic has taken its toll when it comes to public transportation. But on the positive side, it has also helped decrease the number of people who commuted to work/school every day. Although some people rely on private transportation via cars for their commute, they should try to ride their bike or walk if it is a shorter distance.

Viewing my estimated carbon footprint floored me. I entered my data for what my lifestyle was like before COVID-19, and the amount of Carbon emissions I used to contribute through transportation alone on my daily commute to and from school was shocking. Over quarantine, however, I have begun to walk and bike everywhere, which likely has severely lessened my carbon footprint on that front. Since I am now used to those forms of transport, I will seek to continue those carbon-efficient practices into the post-COVID future.
Additionally, I noticed just how much of an impact my meat-eating has on my carbon footprint. The extent to which my decisions to eat pork and beef spiked my carbon emissions have caused me to consider going vegan seriously. Seeing just what I contribute to something like global warming through wastefulness really inspired me to pursue more efficient practices. I believe that practices of carbon-efficient transportation (when possible), as well as vegetarianism or veganism, really could serve to benefit humanity if they were widely adopted under a general species-wide goal of sustainability.

Sustainable fashion is a movement and process of fostering change to fashion products and the fashion system towards greater ecological integrity & social justice. It is important moving foward to do the best we can avoiding fast fashion & shops/ brands that mass-produce. Replacing one fiber type for something less environmentally harmful can make a big change. Fabrics from eco-friendly resources or recyled material can also make a difference. Enviromentally conscious clothing can mean shopping at thrift stores, or any second hand shops (depop, ebay, poshmark, etc.). Even something as simple as donating your old clothes can create change.

Though everyone wants to make a difference on healthy farming the best I feel like you can do it teach younger kids how to grow crops or teach them about sustainable farming. We and them are the future of our world and if we don't teach them at a young age what they can do for our plant we are doing something wrong. Kids should to grow up like me and only learn about sustainability at almost 18. The more you expose kids of agricultural jobs and environmentally helping jobs the more likely they will go into those fields. Show girls they can go into these fields and helps our earth.

Since the invention of the first automobile in 1886 and its' rapid marketization, the United States had gained the nickname "The country on wheels", which meant that the common man was buying an automobile for him or herself. Having at least 1 car per family with typically having only one person in them has been a large contributor to the addition of CO2 in our atmosphere. This could be circumvented by encouraging carpooling, public transport, and electric vehicles. Electric Vehicles can come a long way in terms of prevention of the release of CO2 in the atmosphere, and we should push to make them cheaper and easier to maintain.
