Is the earth we live on is getting worse?The answer is not.But we feel the environment around us is getting worse.The water is polluted,the air we breathe is dirty.Besides the fast growth of population,what we deal with the environment is another key issue.We'd better do something to change the bad habits which wil do harm with the environment.We'd better treat garbages according to their kinds so that we can recycle them.We'd better treat waste waters using more advanced technology.What we can do now is more walk,less car-driving.It's the time to take action.We really need a clean,tidy world.
