Because of the industrialization and urbanization the environment is getting worse. Futhermore the desserts is also growing.  Growing desserts is not good of the earth so we have t find a way to stop growing desserts.  I think making special energies that not bad for environment is the best way to prevent desrtification. Special energes do not cause the air pollution so it will be really helpful. Not only government is trying to make special energies but also people have to endeavor. We can stop desertification by separting collection. After separting collection we can reuse the paper then we don't have to cut a lot of tree. What is related between tree and desertification. Trees can stop desertification. So some people plant the trees in the desserts. So of course we can't stop desertification by creating special energies but we can do separating colllection. Don't think deeply!!
