　　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．
