如何保护环境(How to Protect the Environment)

　　如何保护环境

　　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.
