Animals are natural resources that people have wasted all through our history.
Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in
the way. Thousands of kinds of animals have disappeared from the world forever. Hundreds more are on
the danger list today. About 170 kinds in the United States alone are considered in danger.
Why should people care? Because we need animals. And because once they are gone, there will never
be any more.
Animals are more than just beautiful and interesting. They are more than just a source of food. Every
animal has its place in the balance of nature (生态平衡). Destroying one kind of animal can create many
problems.
For example, when farmers killed large numbers of hawks (老鹰), the farmers stores of corn and grain
were destroyed by rats and mice. Why? Because hawks eat rats and mice. With no hawks to keep down
their numbers, the rats and mice multiplied (繁殖) quickly.
Luckily, some people are working to help save the animals. Some groups raise money to let people know
about the problem. And they try to get the governments to pass laws protecting animals in danger.
Quite a few countries have passed laws. These laws forbid (禁止) the killing of any animals or plants
on the danger list. Slowly, the number of some animals in danger is growing.
