The problems of the environment are more and more important for us.
In this drawing, a family are having a panic on the grass.
They don't really realize they make a serious mistake that they walk on the grass is damage the environment. The small boy is talking photos with his parents, he wears smile on his face.
However, he has been forgetting his study. Look, the sign says"Please don't walk on the grass." Are you not seeing this sign?
The drawing indicates that many people are not concerned about the environment. They don't have a thought that we should protect environment. It is our duty to do something to protect the environment.
I think we can by the way turn off the lights when we want to go outside. And we also can urge anyone not to drop the garbage everywhere.
Let's try our best to product to protect our environment.
