谁能忍受每天戴着防毒面具过日子?——还空气清新吧!
天空是小鸟家，河流是鱼儿的家，地球是我们的家。
让地球妈妈永远年轻美丽。
把绿色带到世界每一个角落，让绿色流入人们心中。
废气，stop!废水，stop!染污，go away!
绿树成荫，花香扑鼻——理想家园靠大家。
破坏环境的人终将得到大自然的惩罚。
节约能源，人人有责!
用好你的手，垃圾无处溜。
地球是我们的母亲，我们要爱护她。
风清水绿天蓝，我们美丽的家。
让天更蓝，让水更清，让我们从小事做起。
我们梦想一个没有污染的环境。
保护环境，人人有责。
捡起一张纸，创造一个美的环境。
陆地、天空、大海，我们都要保护。
谁不爱家?谁不爱妈妈 ——保护地球。
