As we know,many people think the year 2012 is the end of the year.But is that true?Obviously,it is impossible.Now,we do not find any trace to make this happen.However,if we still damage the earth,finally the day will come.Now the pollution is normal and wherever we go,we may find it is around us.
So,I think we must do something to prevent this happen.For example,we should not cut the trees down more and more.You know ,we must try our best to create a good environment for every creature on the earth to live.If we cut down the trees,many animals will lose their habitant and in a long run,many creatures will become endangered and finally extinct.
