How to protect the earth How to protect our earth has become one of the biggest problems in the world.Our earth is just like our mother. We do everything can do a real difference to the earth.We need to pick up litter around us. You"d better join a programme to protect our mother. You mustn"t cut down too many trees. We can protect factories from polluting the rivers.We can do our best to keep the air clear! I hope everyone do these! I believe she will be more and more beautiful!

人們砍伐太多的樹木,到處扔垃圾了。許多工廠把廢物流入河流和湖泊。因此,許多肥沃的土地已經變成了沙漠,留下的只有沙子。許多河流和湖泊枯竭了。空氣變得越來越,髒。地球上的溫度越來越高,越來越高。現在很多人的身體也不好。我認為每個人都應該保護環境。我們可以種植更多的樹木。我們不應該在草地上行走或挑選鮮花。我相信我們的世界將變得和更美麗
