                                                        Save the Animals

     Animals are natural resources(资源) that people have wasted all through our history.

     Animals have been killed for their fur and feathers(羽毛), for food, for sport, and simply because

they were in the way. Thousands of kinds of animals have disappeared from the earth 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 or interesting. They are more than just a source of food. Every

animal has its place in the balance (平衡) 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? 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 animal or plant on

the danger list. Slowly, the number of some animals in danger is growing.
