We need trees

When I was in elementary school, I learned about deforestation. I got the idea that we were losing all the trees in the world, and I love trees! So I decided then and there that I would have a tree of my very own. I'd put a fence around it so nobody could ever cut down "the last tree in the world."

Obviously, I had not yet learned that, without lots of trees, I wouldn't be there to save the last tree. Without trees, the world would be filled with carbon dioxide, lacking the oxygen I would need to breathe, to live. So now that I'm an adult, I want to save not one, but a world-full of trees. (Is "world-full" a word?) We need trees! While we breathe in oxygen and exhale carbon dioxide, trees take in carbon dioxide and "exhale" oxygen. Pretty good system, huh?

So once again, class, why do we need trees? To absorb carbon dioxide and to provide oxygen, for one thing. Let's all do what we can to reduce deforestation. Plant more trees!
