求高手写一篇《Take the care of the earth we live on》

How to take good care of our earth has become one of the biggest problems in the world .
It's our duty to protect our environment .No matter where we live ,we should do something to make our earth a better place for people to live in.We can collect waste paper or other waste things for recycling.We should plant more trees and we should prevent those factories from pouring waste water into rivers,lakes and fields.We shouldn't leave rubbish everywhere and spit in public places.We mustn’t pick the flowers or step on the grass in public.If everyone tries his best to protect the our living space,the world will become much more beautiful and our life will be better and better .
