题目内容
3.It is only during the last few years that man has generally realized that in the world of nature a balance exists (存在 ) between all forms of life.No living thing can exist by itself; it is part of a system in which all forms of life are joined together.If we change one part of the nature order,this will in turn almost certainly bring about changes in some other part.The cutting down of forests reduces the supply of oxygen.The killing of weeds and insects by chemicals leads to the widespread poisoning (中毒) of animals and birds.The throwing of waste products into the ocean hurts life in the sea,while waste gases change the chemical balance of atmosphere and shut out some of the sun's necessary life-giving rays.
And so we could go on,adding more examples,until in despair (绝望) we might feel like giving up the struggle to control and keep within limits these harmful human activities.Man is very clever at changing the world around him to satisfy his immediate need,but he is not so clever at looking far ahead,or at thinking about what the future results of his action might be.Man may well destroy himself in his attempt (企图) to be too ambitious (野心).
