As we all know, there isn't enough(足够的) clean water for people. Many people lose their lives because of a shortage(缺乏) of water. In a lot of countries, people cut down trees for living, so there's nothing to keep water from running away. And we face more and more floods(洪水) and droughts(干旱). Also, we have polluted(污染) the land, the river and the air. It is time that we must do something useful to protect the environment. We can plant trees and take good care of them. We can save the water and ask our parents to do so. We can't throw any litter (垃圾 ) onto the ground and we should collect it for recycling. If we take good care of the Earth today, it can be more beautiful tomorrow.
