Question 1:What bad things do we do to our earth?

Question 2: What should we do?

Care for "Mother Earth"

We all live on the earth. It is our home. There are a lot of trees, flowers, rivers and mountains on the earth. There are also many animals here with us.

Our earth is beautiful. But sometimes we do bad things to it. We cut down too many trees. We waste too much water and make the air dirty.

We have only one earth. We should care for it. We should do something to make the water and the air clean again. We should plant more trees and help the animals.
