Trees and global warming

Lately I have heard so much about the trees and how too many of them are being cut down. My school has just started a new recycling program to save the trees. The reason that the trees are being cut down is because too many people are wasting the paper that they use and not recylcle it at all. Well in my opinion we have alot of trees that we are never going to run out. But today I was told that it takes eight years for a tree to grow enough for the use of paper. That was something that I have never heard before and I can't believe that today was the first time I heard that. The population of trees is reducing more and more every day that is a fact that everyone should know. Well in this case when all the trees are gone all of our animals are going to die off because they have lost homes, food, and shade. That is a natural resource for them and alot of animals can't survive without them. It takes years for a tree to grow not just days like a plant we need the trees for us and animals.
If trees cease to exist then global warming has more of a chance to kill us and animals. This is something that is interresting and can possibly happen I believe, and the way our world is going now then it's possible, one day that our world may cease to exist.
