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 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 of nature. destroying one kind of animal can create many problems. for example, when farmers killed large numbers of hawks, 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 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 the killing of any animal or planton the danger list. slowly, the number of some animals in danger is growing.

動物需要保護

動物是自然資源，在整個歷史過程中，人類一直在糟蹋著這種資源。人們殺死動物，獲得它們的皮毛，把它們當作食物或運動方式，或者只是因為它們礙事。成千上萬種動物已經(jīng)從這個地球上永遠地消失了。現(xiàn)在另外上百種動物也上了瀕危動物名單。僅莢國大概就有170種被認為處于危險當中。

為什么人們應該感到擔憂呢?因為我們需要動物，因為它們一旦消失，就永遠不會再出現(xiàn)。動物不僅僅是漂亮或有趣。它們不僅僅是人類的食物來源。在維持自然平衡中，每種動物都有其作用。毀滅某種動物會導致許多問題。比如，農(nóng)民們?nèi)绻麣⑺罏閿?shù)眾多的鷹，他們谷物和糧食的倉庫就會受到老鼠和田鼠的破壞。 為什么?因為鷹吃鼠類，沒有鷹控制它們的數(shù)量，鼠類就會迅速繁殖。

幸運的是，有些人正在努力幫助拯救這些動物。有些組織籌錢以便人們了解這一問題。他們也努力使政府通過保護瀕危動物的法律。很多國家已經(jīng)通過了法律。這些法

律禁止殺害瀕危名單上的動植物。某些瀕危動物的數(shù)目正在慢慢地不斷上升。
