摘要

Today we can see many people cutting down the trees in the forests. A lot of rich land has become deserts. 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.
