Speach on nature in English

Is this your question, or ...

Nature is important. Nature is vital. If we cut down trees, I'm afraid we'll lose precious oxygen. If we cut down the forests, where will all the animals go? They won't have a home, and more and more they will invade every house in every town in every state. It will be so chaotic we'll have no choice but to exterminate these poor animals, and these animals are important.
