����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.
