Artificial Intelligence

AI is becoming bigger and bigger as the industry and years progress onward. Artificial Intelligence uses gargantuan amounts of water and resources, and is becoming a tool that seemingly all companies want to use. I felt it necessary to talk about and at least put into the minds of some people since it is now becoming commonplace in today's society.

Food Waste

Across the world, food is wasted by restaurants, fast food places, grocery stores, and markets that make or stock more than they can sell. This is incredibly harmful because all of this waste could provide suffering families with the meals that they do not have access to. I think food needs to be made more available to the public by lowering costs of quality, healthy ingredients so that people who are impoverished can still feed their families nutritious meals.

Consumerism

Many people feel pressured to purchase new technology whenever a new version is released because they feel social pressure to always have the nicest phone or the newest airpods. This creates lots of unnecessary electronic waste and could be avoided if people use their devices until they absolutely need new ones.

Extreme Weather

I feel like people who are not directly affected by severe weather events do not fully grasp how much of an effect climate change has on natural disasters. Seasonal hurricanes, wildfires, and tornadoes have become so normalized that unless they are destroying your city, most people will ignore the media coverage because they do not want to accept it as a result of climate change.

Environmentally Friendly Home

If I were the head of my household I would lower my carbon footprint by opting for LED light bulbs because they are more energy efficient than incandescent. I would also compost organic food waste to reduce the amount of waste going to the landfill and to return nutrients to the soil around my home so that I could potentially grow my own fruits and vegetables. I would also opt for energy efficient appliances to avoid burning fossil fuels.

Hold Corporate Accountable

Corporate companies produce immense amounts of pollution that infects our air, water, and land based habitats. Factories are poisoning the air with harmful gases and chemicals, and wasting many valuable natural resources. Corporate CEOs need to be held responsible for the corners they cut in order to make larger profits. Customers also need to shop responsibly and avoid companies that do not take any measures to protect the environment, their employees, or the local community.

Restrictions placed upon corporations

I'm aware that there have been restrictions placed upon corporations regarding their effect on the environment, but to what extent do these restrictions address the issue? As it stands, corporations still make up a large portion of climate change and can operate without much care for the environment. I feel that corporations need more limitations placed upon them so that they will have to take responsibility for their actions. Any thoughts?

Bad Habits

A student's carbon footprint is mostly comprised of actions caused by bad habits. These habits appear in daily life, and the most common are leaving the lights on, taking long showers, sitting in their car with the engine idling, leaving their devices turned on, and not recycling properly. All of these habits are commonplace in many students' daily lives and go unchecked unless someone close to them knows just how bad these habits are. We as a society should be warning these students about how harmful these things are on a larger scale.

Restrictions on emissions

Now is the time to fight against climate change! We as a people need to crack down on the increasing emissions released by companies. As humans, we stray away from restricting businesses and organizations too much because it could affect the economy or progression of technology, but there will be no future if it is not done. You may think I'm exaggerating, but I 100% believe that if nothing is done, the world will become almost uninhabitable within the coming centuries(think of your kids or grandkids). Now then, everyone has a part and contributes a certain amount to climate change, but the majority is caused by organizations or businesses, and it needs to be cracked down on. The time is NOW!

Vertical School Gardens for Lunch MUAHAHAAHAA yum

My big idea is to turn school hallways and cafeteria walls into vertical farms. Most of the food we eat in the cafeteria is trucked in from hundreds of miles away, which creates a massive carbon footprint just for one lunch.

If we grew our own vegetables like lettuce, tomatoes, and herbs right on the school walls, the "food miles" would basically be zero. These gardens use 95% less water than regular farming and don't need pesticides. Plus, having thousands of plants inside the building would act like a massive "carbon sponge," cleaning the air we breathe while we’re in class. It’s a way to make the school self-sufficient and cut down on waste at the same time.

Climate change is real and Humans make it worse

Climate change is definitely real, and so much data proves it.  It's true the Earth’s climate has always changed naturally over millions of years, but the real issue is how fast we’re making it happen now. By burning fossil fuels and clearing out forests, we’re pumping harmful gasses like co2 and methane into the air at a rate the planet can't handle. We're also trashing the oceans and destroying habitats that are supposed to help clean the air. So, even though climate change happens on its own, human intervention is basically putting that natural process on fast-forward and making it way more destructive.

Jamesepic24   2026-01-12 07:46:02 in Is Climate Change Real & Human-Caused?

I absolutely agree with you, Paul Cherney! The Earth's climate is definitely being rapidly changed and warmed by humans. Most of this change is contributed to by massive corporations and businesses, but it's important to remember that we all have a part in this world. This is why I responded to your message in particular, because I appreciate how you consistently used the word "We're", which makes it clear that the problem of climate change is caused by us and therefore needs to be fixed by us.

Think BIG Solar Wrap

We need to implement Solar wrap technology—ultra-thin, flexible solar film that can be wrapped around skyscrapers, paved into sidewalks, and even built into the windows of our school. This would turn every city into a self-sustaining battery. Imagine if your school building produced enough energy not just for its own lights, but to power the neighborhood around it. We wouldn’t need massive, polluting power plants miles away.

Most days, I leave my fan running in my room. This is a habit I got used to because my room is super small, so it is always hot.

Shopping at Malls

It's easy to lose sight of wants and needs when in a third place like the mall, especially when you have your own source of money for the first time. To try and minimize unnecessary spending, I usually try to window-shop, set a budget, and carefully consider whether or not I'll use the things I want. At the end of the day, virtually nothing at the mall is needed, but splurging on yourself every once in a while can be beneficial mentally.

Flying Less

Flying is the biggest way I add to my carbon footprint. Planes use a lot of fuel and release pollution into the air. To cut down on this, I can fly less and take trains or buses for shorter trips. If I do fly, picking direct flights helps because takeoff and landing create the most pollution. Some airlines are working on fuel-efficient planes, and I can also use carbon offset programs to support eco-friendly projects. A big question is how the aviation industry can make flying greener.

27sabol4403   2026-01-09 09:13:13 in Clean Development

Just like you, my carbon footprint suffered massively from the number of flights I take. My dad is a pilot and my mom used to be a flight attendant, so I practically grew up in the air. Direct flights are definitely the best way to reduce carbon emissions without actually traveling less. Even so, I think we should push airlines to find more environmentally-friendly business practices and increase fuel efficiency.

Food Insecurity

I'm sure that some people in some time in their life have heard about food shortages, but do you really know what it means or how bad it really is? Over 295 million people spread over 53 countries that have suffered from food insecurity. That's 5% increase of people losing food from the previous year, according to 2025 Global Report On Food Crisis. People throughout the world should care because this can effect a persons health by chronic diseases, such as diabetes and/or heart problems, also could effect a child's growth, mental health and much more. I believe this topic is important because this affects many people and can be a problem we can all pitch in to help solve and help the people around us all around the world.

27sabol4403   2026-01-09 08:01:51 in Food & Hunger

The drastic increase in food insecurity over the past year signals an issue with the way we live in the modern day. The statistics are concerning, and people are suffering both physically and mentally because they can't get enough nutrition to fuel their bodies. All people deserve to be healthy and fed, even if they live in a food desert or can't afford ample fuel. I agree that this topic is important and should be addressed so we can develop better practices worldwide to help this terrible situation. Whether its spreading the message or encouraging global governments to aid in the crisis, we can all do something to curb food insecurity.

Carpooling

Out of all my friends, I am the only one who has both a driver's license and a car. Naturally, I offer rides to them to/from school and work, and I never thought much about it until recently, when I realized I was unknowingly cutting down on carbon emissions. If I start or end a work shift at the same time as someone else, it only makes sense for us to take one car instead of two.

Climate Change: A glaring modern issue

There was once a time when climate change was merely speculative, a faraway threat nobody needed to address at the time. We didn't think humans would ever see the consequences of reaching greater and greater populations, using more energy and producing more waste and carbon emissions than the Earth can handle. Now, climate change is real, and its a greater threat than ever because we ignored it for so long. Year after year, temperatures have increased drastically as rainforests have been cut down and fossil fuels have been burned. This can only go on for so long; the human population tends to increase exponentially, and the Earth will eventually reach its limit.
Between corporate waste, excessive energy usage, and an unwillingness to look toward the future, we've killed off coral reefs in the ocean and obliterated entire species. This wouldn't have happened without us. We must acknowledge the glaring threat of global warming and work to coexist with ecosystems instead of destroying them. Things won't change unless we all take action together. We can't just pin the responsibility on others when we all inadvertently play a part in this dilemma. Between reducing energy usage, recycling and reusing, and spreading the message about our dying Earth, we can all make a difference together and heal the Earth.

The Issue of Overconsumption

In our modern world, people are inclined to buy things they don't need without thinking. Websites like Amazon make it so easy for people to purchase things at the click of a button without thinking: "Do I really need that?" Additionally, social media trends allow people to promote buying things people want in excess, contributing to waste and environmental decline globally.
Fast fashion is one example of a trendy industry, guided by the whims of people with the most influence. A particular style will be "in" for a week or two and then cast aside and forgotten. As a result, fast fashion companies like Temu and Shein can make low-quality products that fall apart quickly without consequence. Fashion trends are already over by the time the cheap polyester(plastic) clothing falls apart; people move on to the next almost immediately and throw everything else away. The sheer amount of low-quality clothing being wasted is obscene, more than we can feasibly make use of. All around the world, these cheap products go into landfills, slowly stripping the Earth of its health and nature.
This obscene modern trend must be stopped; we need to put more thought into our purchases and consider the future consequences of our actions.

Wants or Needs? Fast Fashion

I think fast fashion is one of the things that seems like a need because everyone wants to keep up with trends, but it's actually a big want that causes a lot of problems. It's tempting because you can get a whole outfit for like $20, but the quality is usually so bad that it ends up in the trash after a month. In my opinion, it's much better to save up for at least a quality piece of clothing that you like instead of buying five cheap things just because they're on sale. Plus, the environmental impact is huge, fast fashion creates so much waste. If more people just shopped at thrift stores or wore their clothes longer, it would save money and the planet.

Corporations Destroying the Environment

Corporations play a concerningly large role in the environmental decline of the modern day. Appliances in previous decades used to be built to last a lifetime, and now they must be replaced every few years. By forcing people to buy low-quality products again and again, corporations contribute to an obscene amount of waste. At the end of the day, all that matters to these big businesses is profit margins, not the increasing frequency of landfills all across the world. Between non-biodegradable plastic products, fast fashion, and water/energy waste during production, corporations are destroying the planet and then pinning the blame on consumers. They pretend to care about the environment, lying about green policies and imploring people to recycle instead of removing harmful business practices. We could do so much to resolve this, whether by imposing legal responsibilities onto these corporations or implementing clean and renewable energy, but doing so requires foresight people don't want to have. Looking toward our future reveals an unpleasant picture of a desolate Earth, and we are more willing to turn a blind eye to this and hope it'll never affect them. Unfortunately, the way things are going, it most certainly will over the course of our lifetimes.

Shorter Showers

Something I am very willing to change would be my shower time. Taking long showers increases our co2 emission because of the gas water heating system in houses. For some people this can be an easy thing to change, but for others it can also be hard. Many people use showers as their time of relaxation and alone time (like me). After a long day all I want to do is stay in a warm shower and relax, but taking a shorter shower will minimize my relaxation time. This would be a challenge I would encounter. Some support that would make my life easier could be to ask for more time alone away from my siblings from my parents.

Danon Raaj   2025-11-18 22:55:59 in Now It's Time for Action

I completely agree! After a long day, I find enjoyment in my showers because they are the one time I can truly relax without any distractions. However, I know how big of an impact long showers have on the environment, and now that I’m aware, I am going to start cutting my time short. Shorter showers use less hot water, which means my water heater burns less energy and produces less CO2, helping reduce my personal carbon footprint. I’ve realized that I can still enjoy my relaxation time without harming the planet, like listening to calming music, or use scented soaps and lotions to make my shower feel luxurious even if it’s shorter. By being mindful and intentional about my shower routine, I can feel refreshed, unwind after a busy day, and still do my part to protect the environment.

landlordcertification   2025-12-08 06:38:45 in Now It's Time for Action

I completely agree with you! Long showers can feel incredibly relaxing after a busy day, but being mindful of our water and energy use really does make a difference. Shorter showers help reduce hot water consumption, lower CO2 emissions, and support a more sustainable lifestyle. I’ve also learned that making small eco-friendly choices at home benefits everyone — just like choosing energy-efficient solutions such as getting an EPC Certificate London Same Day when needed. It’s all about balance. You can still enjoy calming music, scented soaps, and a peaceful routine while also protecting the environment through simple, intentional habits.

Is there any real way to stop Climate Change now?

Climate Change is a consequence of the rapid industrialisation of the world and human neglect/unawareness of pollution. The industrial revolution, while an important event in modern history, also kickstarted industrial pollution and as a consequence caused climate change. Are there any real ways to prevent it, or does the current political landscape not allow any such preventive actions to be put in effect due to the favoritism showed to corporations, industrialists and how they see these preventive actions as 'non-beneficial'?

TAy98321   2025-11-19 20:26:48 in Is Climate Change Real & Human-Caused?

this makes a lot of sense and i understand what you mean by "are there any real ways to prevent it..." i do think there are at least a couple but they might not be possible at this point in climate change.

BoopDoopC   2025-12-07 10:34:03 in Is Climate Change Real & Human-Caused?

"STOP" and "NOW", absolutely not, "lower drastically" and "over the next decade or so", very possible.
if all of humanity managed to agree to some policies and promises then we could likely meet the goal of less than 2°C by 2030 (maybe 2040)
1st we need to stop all burning of coal NOW,
coal is by far the worst, dirtiest, and least efficient fossil fuel, its a technology that belongs in the industrial revolution.

2nd we need better public infrastructure,
while one train (even electric) produces more co2 by itself than a car, if a hundred people are in that train then that train produces much less greenhouse gases per person than a car, so the answer is more electric trains, subway systems, electric ferries to islands, and electric busses where applicable, its also not just enough to have these things we need to

2.5lf encourage people to use public infrastructure and discouraging use of cars
cars are convenient sure but they pollute a lot, if we could make parking harder to find, more walking streets, one ways, reduce the number of lanes on highways, trains that run on time, and better accommodations, for example on one of these points, LA opened a new lane on one of their highways a few (dozen) years ago, and congestion got worse over the entire city, because people found it more convenient driving they would drive more and thus more cars on the roads, and that has lead to a joke in civil engineering "just one more lane and that will solve it"

3rd the world needs to transition away from coal, oils (petrol, diesel, crude oil), biofuels, and natural gas,
some fuels are less bad than others, for example crude oil and coal are much less preferable over the RELATIVELTY clean natural gas and biofuels, still not ideal fuel sources but just better if for example cargo ships run on biofuel over crude oil.
so we need to adapt industry away from that, foundries need to use preferably something like hydrogen gas or induction heating ovens,
ships need to use more efficient fuels or even hybrid ships (electric ferries for shorter trips are amazing (trust me, I'm on one right now))

4th we need cleaner powerplants to run this new industry. lets say we get every company and industry on the planet to somehow go fully electric, we still need the source of that electricity to be clean or we are just moving the problem from the production to the source. solar, wind, hydro, and geothermal, are obviously the goal and the best for this, but we need a ton of electricity it in a very short time, so might I suggest nuclear energy,
nuclear energy is much safer than people imagine (I mean global warming kills more people per year than nuclear energy ever has,) fossil fuels also contaminate more than nuclear and produce waste that goes into the air and is harder to manage than barely radioactive rocks that you can reuse 97% of and then throw the waste into a hole. because nuclear energy is so scrutinized that means that like airplanes its one of the safest forms of doing what they do, any time anything goes wrong everyone is talking about it so they have to hire the smartest people they can to make sure everything is safe.
another benefit of nuclear energy is that the only waste is a rock you burry a few kilometres underground to safely decay, and some water vapour that condenses back into safe water.
