EcoCity

In a city like EcoCity, the focus would be on reducing carbon emissions and promoting a sustainable lifestyle. There would be a good public transportation system, like trains and electric buses, so people can move around easily without needing cars. Buildings would be energy-efficient and use renewable energy sources like solar power. There would be lots of green spaces and areas for recycling and composting. Living in EcoCity would mean having access to modern urban life while also caring for the environment.

Sustainable city

In my opinion,nature is our best friend and we need to protect it at all costs! A way to protect is planting more trees. Our city can be more sustainable and organized. The trees gathers the carbon dioxide, protecting us from its danger.

Sustainable City

I believe that in order to be able to improve the cleanliness of my city, it is necessary to add as many trash cans as possible, each one for a certain category, either paper, or plastic, or cardboard, and that there are no more normal trash cans. In this way we make the work of garbage collectors easier.

Sustainable city

There are many things we can do to make the city more sustainable, and we can start by reducing energy consumption at home by replacing regular light bulbs with LED ones and by using energy-efficient household appliances. We can also use public transport or a bicycle instead of a personal car to reduce pollution

Reducing the carbon footprint

In my opinion a way to reduce the carbon footprint in a city is by promoting renewable energy sources like wind or solar power.

Sustainable City

In this city, imagine a network of pedestrian-friendly streets lined with bike lanes and green spaces, encouraging walking and cycling. Public transportation would be efficient, powered by renewable energy sources, and easily accessible to all residents. There would be an emphasis on mixed land use, with neighborhoods designed to reduce the need for long commutes. Renewable energy sources like solar panels and wind turbines would dot the landscape, providing clean power for homes and businesses. Waste management would prioritize recycling and composting, minimizing landfill waste. It sounds like a city designed for a sustainable future, and definitely a place I'd consider living in!

Reducing the carbon footprint

I think one of the ways we can reduce the carbon footprint of a city is restricting the usage of old and polluting cars.

cold fusion is kinda sick

Cold Fusion, or low-energy nuclear reaction (LENR) is basically a hypothesized type of nuclear reaction that should occur at room temperature. There is currently no widely accepted theoretical model that would allow cold fusion to occur.

Theoretically, it should provide virtually LIMITLESS energy and minimal nuclear waste, and pretty much no environmental impact compared to, say, fossil fuels.

See, current nuclear power plants use nuclear fission (not fusion), which, as the name suggests, consists of splitting heavy atoms (such as uranium-235 or plutonium-239) into smaller fragments, which releases a large amount of energy. The problem is, along with energy, fission also produces additional neutrons and radioactive fission products.

These radioactive fission products are typically unstable isotopes of elements such as cesium strontium, iodine, and plutonium. These isotopes decay and emit radiation in the form of alpha, beta, and gamma particles. Some of these isotopes can remain for thousands to millions of years.

Cold fusion, on the other hand, is a nuclear reaction which is quite frankly the opposite of fission. It involves two like atomic nuclei (often involving hydrogen isotopes such as deuterium and tritium) merging together to form a heavier nucleus (helium nuclei), releasing a significant amount of energy in the process. he energy released is due to the conservation of mass into energy, described in Einstein’s famous equation, E=mc^2, because if you look at the mass of the reactants and compare it to the mass of the product, you’ll find that its not equal, which means some of the mass has been transferred into energy.

The reason this occurs is because the speed of light (c) is a very large number, even the smallest of mass could theoretically be converted into a large amount of energy. This process occurs at near room temperature. This low energy requirement reduces harmful nuclear byproducts. Hydrogen isotopes are also relatively lighter than nuclear fission reactants, and therefore should generate more stable elements.

If we can somehow harness this release of energy, it could be a potential source of clean and abundant form of energy, proving to be superior to the fossil fuel and nuclear fission energy we use today…

(if ya read all of that congrats u officially don't have the attention span of a 6 year old yayyy)

Global Warming

Did you guys notice that it has been so hot lately? It is just April and I could die of heat. AC are on everywhere I go. But, why is this? The reason is because of GLOBAL WARMING. It is is the long-term heating of Earth's surface observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere. Because of global warming, many animals are dying. The polar bears in North Pole are dying because of the heat. The ice that they are living on are slowly melting. In a few decades, or even less, they are going to be no ice. They are all just going to die!

The polar bears are not just going to be the target of global warming. We, humans, are also going to be targets. This is because in a few decades, the temperature on Earth might be 50 degrees or more. Can humans survive this temperature? I don't think so. Maybe humans can't even survive 40 degrees. Don't say that this is not possible. These few days in Taiwan are 30 degrees. It is only April!!! So maybe next few years will actually be 40 degrees!

Global warming is actually a cycle. First, people invented the AC because it gets too hot during the summer. When people used it in the summer, the inside stays cold, but in contrast, hot air will be released into the atmosphere. Slowly over time, it gets hotter and hotter everywhere around the world. Humans can't stand a little hot, so they will turn on the AC. So it goes on and on and on. Until maybe the winter won't be cold anymore. No more spring, fall, or winter. Summer all year!

In conclusion, global warming is a serious issue on Earth. If we don't fix this problem, we are all going to die. You can reduce this issue by saving energy, such as using fans instead of AC or turn off the light if you are not using it. You can also walk to places if they are close to your location or prevent driving cars and take public transportation with many more people. You can stop wasting food and reduce, reuse, and recycle. By accomplishing these steps, you will not only make a huge change to yourself, but also a huge change to the world.

Climate Change is Definitely Real & Human Caused

Climate change is one of the biggest problems we have in the world today. It is defined as "long-term shifts in temperatures and weather patterns". Climate change can cause a lot of things such as droughts, severe storms, warmer temperatures, and rising oceans. This is really happening today and humans should be the ones to stop climate change from getting worse because humans are the ones who caused it. It is true that humans have caused climate change because of burning fossil fuels and chopping down trees. Humans really should start taking action to stop climate change.

Recyling

What is recycling? Recycling is the process of collecting and processing materials that would otherwise be thrown away as trash and turned into new products. A lot of public spaces have separate trash cans one in which for recycling and the other for normal trash. Now you might wonder how much percent of trash we can recycle. According to recycling. bins.com about 80% of the things we throw away could be recycled. Now many may say that recycling is a failure since only about 5-6% of plastic gets recycled in the USA. However, this may be because of several issues such as poor advertising, and humans feeling greedy. Now how can we fix this? In accordance with several reports, recycling campaigns have been useful in addressing the issue. There can also be laws that can be established regarding recycling and usage of products.

Some countries have already taken action such as Germany, France, Japan, and more. These countries have banned the sale of single-use plastic straws, cutlery, cotton buds, and food containers. Some other things that can help tackle the issue are if supermarkets ban the use of plastic bags and stop providing them to their customers. Instead, we could all bring our reusable bags. In addition, we can donate items that are still in good, usable condition to charities. Not only that but at the Christmas season we often wrap our gifts with wrapping paper and then throw them away. However, if the wrapping paper is not wrapped/destroyed why don't we reuse it so that we don't have to rebuy some next year?

  Why is recycling important? More and more people recycle every day. This helps reduce landfills and more costly forms of disposal. Recycling also lessens the requirement for raw material extraction (mining, quarrying, and logging), refining, and processing—all of which significantly contaminate the air and water. By lowering greenhouse gas emissions and promoting energy conservation, this helps combat climate change. Recycling prevents countless tons of rubbish from ending up in landfills. Recycling reduces carbon emissions in the UK by 10–15 million tons annually, which is the same as removing 3.5 million automobiles off the road.

  I encourage you to try to recycle as much as you can to create a positive impact on the world. Every bit helps!
