Protection of the Environment Once man did not have to think about the protection of his There were few people on the earth, and natural resources seemed to be Today things are The world has become too We are using up our natural resources,and polluting our environment with dangerous If we continue to do this, human life on earth will not We realize that if too many fish are taken from the sea, there will soon be none Yet,with modern fishing methods, more and more fish are We know that if too many trees are cut down, forests will Yet, we continue to use powerful machines to cut down more and more We see that if rivers are polluted with waste products, we will Yet, waste products arestill put into We know that if the population continues to rise at the present rate, in a few years, there won't be enough What can we do to solve these problems? If we eat more vegetables and less meat, there will be more food Land for crops feeds five times more people than land where animals are Our natural resources will last longer if we learn to recycie The world population will not rise so quickly if people use modern methods of birth Finally, if we educate people to think about the problems we shall have a better and cleaner planet in the 保护环境 过去,人们不必担心保护环境的问题。 因为那时地球上人口稀少,自然资源似乎取之不尽。 如今,一切都改变了。世界变得拥挤异常。我们正在耗尽我们的自然资源,有毒化学制品的使用也正污染着环境。如果我们继续这样下去,地球上的生命将不复存在。 我们都知道如果从海里捕捉太多的鱼,海里就不会再有鱼了。但是,现代化的捕鱼技术使得捕鱼量越来越大。我们都知道如果砍伐太多的树木,森林就会消失。但是,我们仍旧使用强大的机械砍伐越来越多的树木。我们都知道如果河水被废弃物污染的话,我们只有死路一条。但是废弃物仍然源源不断地进入河里 我们知道,人口继续照现在这个速度增长的话,不出几年,就会发生食物短缺。我们该如何解决这些问题呢? 如果我们多吃蔬菜,少吃肉类的话,我们就会有更多的食物。因为同样大小的土地如果种庄稼的话会比养殖动物多养活五倍多的人。 如果我们学会再利用的话,自然资源就能持续更久。 如果人们使用现代化的生育控制方法,世界人口就不会增长如此迅猛。 最后,如果我们能够教育人们都意识到这些问题的话,未来我们就会有一个更好、更洁净的星球。
