We have only one earth ,so it is important to protect the environment. First, we should live a low-carbon life, we'd better travel by bike or on foot instead of taking a car. We should take a bag with us when we go shopping instead of using plastic bags. We'd better not waste electricity,paper and so on. Secondly, we shouldn't spit in public or litter things. We should put the rubbish into the dustbin. We'd better plant more trees, grass and flowers instead of cutting down the trees. I believe if everyone makes a contribution to the environment, our world will become more and more beautiful.

我们只有一个地球，所以。保护环境是非常重要的。首先，我们应该过低碳生活。我们因该用骑车或步行替代开车。购物时，应该自己准备袋子而不应该使用塑料袋。我们不应该浪费纸张和电力等等。其二，我们不应该在公共场所随地吐痰或乱丢杂物。垃圾应该进垃圾桶。我们应该多植树，种草种花，不应乱砍乱伐。我相信，如果每个都做出贡献，我们的世界就会变得更加美丽。
