It's our duty to protect our environment . No matter where we live , we should do something to keep our neighborhood clean and tidy . We can collect waste paper or other waste things for recycling 中考. 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 environment , the world will become much more beautiful and our life will be better and better .
