Environmental's problems

Environment has a lot of problems because humans don't do anything to prevent them. There is a large list of the disadvantages of not being green, therefore it is imposible to talk about all problems. Not the whole world is conscious about what is happening in another places of Earth. We are going to focus in the problem of cutting down trees. Per month there is an amount of more than 100.000 cutted trees. This means that if we only chop down trees, then is going to come a time when we will run out of them. That is a really big problem. We aren't conscious that trees maintain us alive. Firstly, trees and plants give us oxygen and secondly, they catch the CO2 which it is bad for the environment. The solution to this problem could be the announcement of an official day in the whole world to plant trees in every big city, town, villages and also why not in the countryside. We have to know that when we cut down trees, we are killing ourselves.
