How to Protect the Environment   

    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.
