阅读下面的短文,并根据短文后的要求答题(请注意问题后的词数的要求).

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

     Why should people care? Because we need animals. And because once they are gone, __________________

_____________________________________________. Animals are more than beautiful or interesting or a

source of food. Every animal has its place in the balance of nature. 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 to protect animals in danger.

     Quite a few counties have passed laws. These laws forbid the killing of any animal or plant on the danger

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