志愿者的英语作文 50词左右，要求写保护环境的志愿者，用一般将来时 be going to 结构，急！

We have only one earth. But now,the environment becomes worse and worse.
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 the land, the river and the air. So we have to face more and more floods and droughts .
It's time that we must do something useful to protect our 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 onto the ground and we should collect them for recycling.
