  Why are plants important
  Today I am at home. I talked about plants with my family. I know why plants are so important for us.
  There are many plants around us. And we can't live without plants. Do you know why? Let me tell you. Plants help clean the air and it is pleasant to walk among the trees. We also can get the food from plants. Such as apples, oranges and so on. Corn, wheat and rice are all plants, too. We can make and build things with trees -- like chairs, beds and houses! We can sit under a tree in the shade in summer. Plants cover the soil. Plants stop wind and water from carrying the soil away. All plants take energy from the sun and make it into food. People and other animals need food to live. So we need plants. Plants are very important.
