     It is reported that conservation groups in North America have

been arguing about the benefits and dangers of wolves. Some groups

believe wolves should be killed. Other people believe wolves must be

protected so that they will not disappear from the wilderness(荒野).

                           For Killing Wolves

     In Alaska, the wolves almost disappeared a few years ago,

because hunters were killing hundreds of them for sport.

However, laws were established to protect the wolves from

sportsmen and people who catch the animals for their fur. So

the wolf population has greatly increased. Now there are so

many wolves that they are destroying their own food supply.

      A wolf naturally eats animals in the deer family. People in

the wilderness also hunt deer for food. Many of the animals

have been destroyed by the very cold winters recently and by

changes in the wilderness plant life. When the deer can't find

enough food, they die.

     If the wolves continue to kill large numbers of deer, their

prey(猎物)will disappear some day. And the wolves will,too.

So we must change the cycle of life in the wilderness to balance

the ecology. If we killed more wolves, we would save them and

their prey from dying out. We'd also save some farm animals.

     In another northern state, wolves attack cows and chickens

for food. Farmers want the government to send biologists to

study the problem. They believe it necessary to kill wolves in

some areas and to protect them in places where there is a small

wolf population.

                     Against Killing Wolves

    If you had lived long ago, you would have heard many

different stories about the dangerous wolf. According to most

stories, hungry wolves often kill people for food. Even today,

the stories of the "big bad wolf" will not disappear.

       But the fact is wolves are afraid of people. and they seldom

travel in areas where there is a human smell. When wolves eat

other animals, they usually kill the very young, or the sick and

injured. The strongest survive. No kind of animal would have

survived through the centuries if the weak members had lived.

And has always been a law of nature.

     Although some people say it is good sense to kill wolves,

we say it is nonsense! Researchers have found wolves and their

prey living in balance. The wolves keep the deer population

from becoming too large, and that keeps a balance in the

wilderness plant life.

    The real problem is that the areas where wolves can live

are being used by people. Even if wilderness land is not used

directly for human needs. The wolves can't always find enough

food. So they travel to the nearest source, which is often a

farm.Then there is danger. The "big bad wolf" has arrived!

And everyone knows what happens next.
