Trees' Functions

As we know, trees are important to us humans. They can make our environment more beautiful and make the dirty air cleaner. They are good for our health, too. Trees can not only be used to build houses and make paper, but they can also be used for making many other things. For example, many things in our houses are made of wood. What's more,trees can stop the water from washing the earth away. So we must protect trees and plant more trees. We mustn't cut down trees freely. In this way,we can keep the balance of nature and we humans and animals can live a happy life on the earth.
