How to protect the environment 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 keep our neighborhood clean and tidy . 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 environment , the world will become much more beautiful and our life will be better and better .

如何保护环境已成为世界上最大的问题之一。

这是我们的责任来保护我们的环境。不管我们生活在哪里,我们应该做些事情来保持我们的邻居干净和整洁。我们可以收集废纸或其他废物回收。我们应该种植更多的树,我们应该阻止那些工厂将废水流入河流,湖泊和田野。我们不应该把垃圾无处不在,在公共场所吐痰。我们不能摘花在公共场合或在草地上一步。如果每个人都尽力保护环境,世界将变得更加美丽,我们的生活将越来越好。
