谁能翻译一下
Once man did not have to think about the protection of his environment. There were few people on the earth, and natural resources seemed to be unlimited.
Today things are different. The world has become too crowded. We are using up our natural resources,and polluting our environment with dangerous chemicals. If we continue to do this, human life on earth will not survive.
We realize that if too many fish are taken from the sea, there will soon be none left. Yet,with modern fishing methods, more and more fish are caught.We know that if too many trees are cut down, forests will disappear. Yet, we continue to use powerful machines to cut down more and more trees. We see that if rivers are polluted with waste products, we will die. Yet, waste products are
still put into rivers.
We know that if the population continues to rise at the present rate, in a few years, there won’t be enough food.What can we do to solve these problems?
If we eat more vegetables and less meat, there will be more food available. Land for crops feeds five times more people than land where animals are kept.
Our natural resources will last longer if we learn to recycie them.The world population will not rise so quickly if people use modern methods of birth control.
Finally, if we educate people to think about the problems we shall have a better and cleaner planet in the future.

以前人类不去考虑保护环境~少量的人们生活在地球上时并认为能源是无穷的.
现在就不一样了,人口多了,我们用光了自然的能源,并且我们的环境被危险的化学品污染了,如果我们继续这样,人们不可能再存活下来~
我们了解到如果许多的鱼从海里被打捞上来,大海里的鱼将被打捞干净~伴着现代的捕鱼技术的发展,越来越多的鱼被打捞上来~如果大树总被砍伐,森林将消失,但是我们仍然用现在的强大的工具去砍越来越多的树,我们意识到,如果河流被废品污染,我们将会死,但废品仍然被倒进河里.
我们知道如果污染继续增加,在一些年内,不会再有足够的食物,我们怎么做才可以解决这个问题呢?
如果我们多吃蔬菜少吃肉类,就会有许多富余的食物,谷类有人们和动物5倍的地方来种植.（可能不准确,不知道要怎么说出来...）
我们的自然资源会使用的长久一些如果我们利用好他们.世界的污染将不会上升的这样快如果人们控制人口.
最后,如果我们教育人们去思考一个问题就是我们将来应该有一个跟好的更干净的星球.
