　　 I think the picture shows us our beautiful earth on which we live. I can see in the picture green grass, trees and butterflies flying happily here and there. What a peaceful and beautiful sight! I can also see a hand, which, I think, stands for every citizen. As is known to all, our earth is being polluted. A lot of animals are endangered. To protect our environment and live in harmony with animals is every citizen’s duty. Only when we realize the importance of our environment can we really do something to solve the problem of pollution.
