My second inquiry is “How human activities change the CO2 level”. Carbon Dioxide is well known as the ‘greenhouse gases. The greenhouse gas is produced by burning many sorts of forms. Human activities are the main producers of Carbon dioxide. They burn oil, coal, trees, trash, and everything else they can get their hands on. Oil, coal, gas, and fossil fuels contain carbon. When it is burnt (which we do often), we release them as carbon dioxide through smoke.
Another of men’s mischievous doings are deforestations. Deforestation is when you cut trees in order to make new farmlands or build places. They can also be cut down just to make paper and other items made from wood. Trees (1) have Carbon contain in them as they absorb it in a process called photosynthesis and (2) produce Carbon Dioxide when they are burnt. Trees help us but we’re destroying them. One of the worst cases of deforestation is when you have to do it again and again. When you cut down trees, you provide farmland to make farms. But because the world is starting to get hotter, the land would dry up fast and allowing us to do it again. By this, we increase the level of Carbon Dioxide more and more.

This is what we should do to help our environment, infact, this picture is taken from Indonesia.
