Today we can see many people cutting down the trees in the forests. A lot of rich land has become deserts（沙漠）. If we read newspapers，we’ll learn that the forests on the earth are getting smaller and smaller all the time. We are cutting down large numbers of trees because we need wood and farmland. Some scientists say that there will not be any great forests in 20 or 30 years.
　　What will happen if the forests disappear？A lot of plants will die and the animals will lose their home. In many places the new farmland will soon look like the old deserts. Crops（农作物） will not grow there. There won’t be enough rain，and the weather will get hot and dry. If the climate of the earth changes，life will be hard for everyone. Our living environment will become worse and worse. More and more rich farmland will disappear.
　　It’s our duty to protect the forests well. Everyone should try his best to make a contribution（贡献） to taking care of the forests. Stop cutting down the trees and make the world greener！
