Good environment can make people feel happy and fit 。 To improve the environment means to improve our life。

　　We should plant more trees and flowers around us 。 We shouldn’t cut them down 。 We should stop factories from pouring waste water into the river and waste gas into the air。

　　Whenever we see litter on the ground ， we should pick it up and throw it into dusbins。 Never spit in public。 Don’t draw on public walls。 It’s our duty to protect the environment。
