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.
