【題目】Wilderness

“In wilderness(荒野) is the preservation of the world.” This is a famous saying from a writer regarded as one of the fathers of environmentalism. The frequency with which it is borrowed mirrors a heated debate on environmental protection: whether to place wilderness at the heart of what is to be preserved.

As John Sauven of Greenpeace UK points out, there is a strong appeal in images of the wild, the untouched; more than anything else, they speak of the nature that many people value most dearly. The urge to leave the subject of such images untouched is strong, and the danger exploitation(開發(fā)) brings to such landscapes(景觀) is real. Some of these wildernesses also perform functions that humans need—the rainforests, for example, store carbon in vast quantities. To Mr.Sauven, these ”ecosystem services” far outweigh the gains from exploitation.

Lee Lane, a visiting fellow at the Hudson Institute, takes the opposing view. He acknowledges that wildernesses do provide useful services, such as water conservation. But that is not, he argues, a reason to avoid all human presence, or indeed commercial and industrial exploitation. There are ever more people on the Earth, and they reasonably and rightfully want to have better lives, rather than merely struggle for survival. While the ways of using resources have improved, there is still a growing need for raw materials, and some wildernesses contain them in abundance. If they can be tapped without reducing the services those wildernesses provide, the argument goes, there is no further reason not to do so. Being untouched is not, in itself, a characteristic worth valuing above all others.

I look forwards to seeing these views taken further, and to their being challenged by the other participants. One challenge that suggests itself to me is that both cases need to take on the question of spiritual value a little more directly. And there is a practical question as to whether wildernesses can be exploited without harm.

This is a topic that calls for not only free expression of feelings, but also the guidance of reason. What position wilderness should enjoy in the preservation of the world obviously deserves much more serious thinking.

1John Sauven holds that_____.

A. many people value nature too much

B. exploitation of wildernesses is harmful

Dear Bill,

You must know how deeply saddened I was over your loss. Your sister and I were the dearest friend and recalling the past, I dare saying she was like a sister to me. I will miss him very much.

I could always count at her whenever I needed help, whether with a big project and a small task that she was always so willing to help me with. I came to trust her judgment and wise as well and her advice were always so well thought out and helpful.

She was a terrible great friend and I know our lives will never be same without her. I could never find a better and more caring friend. She has been left us with so many wonderful memories. I will cherish them forever.

In Deep Sorrow,

Betty Smith
