2. Let’s do something to save the earth.
3. Forests give us a lot of valuable things.
4. Vegetation can help conserve water.
B. Man and most animals need a constant supply of water to live. Farmers need water for their crops. Hydroelectric dams hold back needed water and provide power for homes and industries. Trees, grasses, and other plant life play an important part in the natural circulation of water, and thus help conserve it. Without plants, most water would run off as soon as it falls, talking away valuable soil. Rapid run off would cause frequent floods and leave little water during dry seasons.
