Here in Alaska, the wolf almost disappeared a few years ago, because hunters were killing hundreds of them for sport. However, laws were passed 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 lives on animals in the deer family. People there also hunt deer for food. Many of the animals have been destroyed by the very cold winters recently and by changes in the plant life there. When the deer can’t find enough food, they die.
If the wolves continue to kill large numbers of deer, the deer will disappear some day. And the wolves will, too. So we must change the life cycles there. If we killed more wolves, we would save them from starving. We also save deer and some farm animals.
In another northern state, wolves attack cows and chickens for food. Farmers want the United States government to send a team of scientists to study the problem. They believe it is necessary to kill wolves in some areas and to protect them in places where there is a small population.
