     In some places in North Africa, great cities once stood. There were   gardens and trees and grass.

But  now  these  places are like  deserts.   Scientists have begun to  study this land   to  find out what

happened. Many of them think   the land died when the trees were cut down. Trees help  other plants

grow. Tree roots hold the earth in place. They stop the soil from being blown away. In forests, leaves

on the ground  keep rainwater from running off. Trees near farmer protect growing plants from strong

winds.

     Once there were hundreds of farms in the Southwestern United States. Then the farms turned into

fields of dry land, because few trees grow in the dry Southwest.

     Now we try to save trees. In many forests, when  a  tree is cut  down,   a new tree is planted in its

place. We do not want the land to die.
