There's so much pollution in the air now that if it weren't…

People havealways polluted the environment. There is so many carbon dioxide in the air, and now there are less trees. There are many trees in the nature, and people burn and cut them for their own needs, such as making a paper from tree. The climate has changed a lot too. You can't the real winter in Russia anymore, and there is the way hotter in the summer than it should be. So if we keep on like this, the Earth will be destroyed!
