¡¡¡¡Animals and people can get food from plants. Without plants life will not go on.

¡¡¡¡Trees and plants can make the air clean. They can keep the water from flowing away. They can stop the wind from blowing up sand and earth.

¡¡¡¡But in some places people are cutting down too many trees. This brings about floods and sandstorms.

¡¡¡¡Now more and more people know plants are important. They will plant more trees and grow more plants. They will do their best to protect them. And our country will be more beautiful.
