The Importance of Plants

We all know plants are very important to us humans, animals and the environment we live in. Now, let me introduce the importance of plants to you.

Plants give us basic needs. People can eat plants or use them as medicine. People use wood from trees to build houses and furniture. Our clothes are also made from plants. Books, paper, pencils and erasers all come from plants. Animals live in the forest and eat the fruit from the trees. Plants also help make the air clean and fresh. They cover the soil and can stop the wind. In a word, all of us cannot live without plants. The plants are important.
