Animals are natural resources that people have wasted all through our history.
Animals have been killed for their fur and feathers(羽毛), for food, for sport, or simply because they were in the way. 16 kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in 17 United States alone are considered in danger.
Why 18 people care Because we need animals. And because 19 they are gone, there will never be any more.
Animals are more than just beautiful or 20 . They are more than just a source of food. Every animal has 21 place in the balance of nature. Destroying one kind of animal can create many problems.
For example, when farmers killed large numbers of hawks (鹰), the farmers’ stores of corn and grain were destroyed by rats and mice. Why 22 hawks eat rats and mice. With no hawks to keep down their numbers, the rats and mice multiplied (繁殖) quickly.
23 , some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try 24 the governments to pass laws protecting animals in danger.
Quite a few 25 have passed laws. These laws prohibit(禁止) the killing of any animal or plant on the danger list.
