    　　If you travel by air across the centre of Africa or south.

    　　America, you fly over forests for thousands of kilometres. These great forests are the oceans of trees. There are full of thousands and thousands of different kinds of plants and animals.

    　　However, the worlds forests are getting smaller all the time. We are cutting down the trees because we need wood, and we need more farm land. Some people say that there will not be any forests like these in 20 or 30 years. What will happen if they disappear?
