Trees are useful to birds and animals. Trees give them food and homes. Trees are useful to us. They give us wood. We use wood to make houses, paper and many other things. Trees give us fruit. Trees give us oxygen. They help keep the air clean. They protect us from sandstorms and floods. But we cut down too many trees. Many birds and animals lose their homes. Our Earth becomes hot and dirty. We should save trees and plant more trees.
