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.
For
Killing Wolves
In
Alaska,the wolf almost
disappeared a few years ago,because
hunters were killing hundreds of them for sport.However, 1aws 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.That 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.
