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 shouldnt 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. Dont draw on public walls. Its our duty to protect the environment.
