The earth is our home. But it is becoming worse and worse. I think we should do as the followings:
First, it is better to ride a bike to school instead of taking a bus or a taxi. Second, we should remember to turn off the lights when we leave a room. Third, we’d better not use plastic bags, because they are not only harmful to our environment but also bad for our health. Last but not least, we should stop cutting down trees and try our best to plant more trees. After all, we have only one earth.
The earth is crying for help. We should do everything we can to protect it.
