Shrinking Forests The world’s forests are getting smaller. Sometimes nature causes forests to shrink. Storms can knock down trees. Usually people cause forests to shrink. We cut down trees for wood and paper. We clear forestland to make farms and neighborhoods. Luckily, people are changing how they treat forests. We recycle paper, so fewer trees need to be cut down. Companies that cut down trees plant new ones. These changes can stop the forests from shrinking. 20

We Need Forests • Wood is used for fuel, paper, furniture, and homes. • Trees help make oxygen. Oxygen is a gas in the air. All animals need oxygen to breathe. • Millions of plants and animals live in forests. • Roots hold soil in place so the rain doesn’t wash it away. • People enjoy camping and hiking in forests. 21
