Unit 2 The EnvironmentProtecting the environmentEnvironmental problems are becoming more and more serious all over the world. As the world becomes more crowded, we are running out of our natural resources more quickly. In particular, we are polluting our environment. Large quantities of poisonous gas are being let off into the atmosphere, and other types of waste are flowing into the water.Moreover, forests have decreasedbecause many trees are being cut down. As is known to us, trees can absorb carbon dioxide and produce oxygen. As a result, the problem of global warming becomes more serious.So it's our duty to try to cut back on production. We should try to find ways of recycling our waste. Sometimes human beings are too greedy, and we should take responsibilities to protect our environment.In my opinion, effective measuresmust be taken to protect our planet. We should live a lowcarbon life. I'm sure we shall have a better and cleaner planet in the future.保护环境全世界的环境问题正变得越来越严重。随着世界人口激增,我们正加速消耗我们的自然资源。特别是我们正在污染环境。大量的有毒气体正被释放进大气层。其他种类的废弃物则流入水里。而且,由于树木被砍伐,森林面积逐渐减少。我们知道树木能够吸收二氧化碳,释放出氧气。结果,全球变暖这一问题变得更加严重。因此我们有义务减少产量。我们应当努力找出循环利用废弃物的方法。有时人类太贪婪了,我们有责任保护我们的环境。我认为,必须采取有效措施来保护我们的星球。我们应当过一种低碳生活。我确信我们的星球在将来将变得更美好、更洁净。1
