As you know, there’s no enough clean water for people. So many of them lose their lives because of water. In a lot of countries, people have to cut trees for living. So there’s nothing to keep water from running away. Also we have polluted (污染) the land, the river and the air. So we have to face more and more floods (水灾) and droughts (旱灾). It’s time that we must do something useful to protect our enviroment. We can plant more trees and take good care of them. We should save water. We can collect dirty water for recycling. We shoudn’t throw rubbish anywhere. If we take care of our Earth today, it will be more beautiful tomorrow.
