Reading comprehension:

Now scientists are trying to turn deserts into good land again. They want to bring water to the deserts, so people can live and grow food there. However, more and more land is becoming the deserts. Why is this happening? There are two reasons—land and wood. In many places the trees have been cut down because the land was needed for people.

In other parts, the trees are cut down because their wood is wanted. But many people don’t know that in most places the trees won’t be replaced （取代） . The soil in the forests is very thin, but it is protected by the trees. When the trees are cut down, the soil is washed away by the rain or blown away by the wind. Soon nothing can grow on it. The land becomes a desert.

Who is to blame （应负责、责备） for

this? The answer is easy: all of us.

There are just too many people in the

world. The world’s population is now

six billion. You might say: We don’t cut

down trees. Yes, but just look around.

You’re probably using its products （产品） right now.
