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(dòng)物需要保護(hù)

動(dòng)物是自然資源，在整個(gè)歷史過(guò)程中，人類一直在糟蹋著這種資源。人們殺死動(dòng)物，獲得它們的皮毛，把它們當(dāng)作食物或運(yùn)動(dòng)方式，或者只是因?yàn)樗鼈兊K事。成千上萬(wàn)種動(dòng)物已經(jīng)從這個(gè)地球上永遠(yuǎn)地消失了?，F(xiàn)在另外上百種動(dòng)物也上了瀕危動(dòng)物名單。僅莢國(guó)大概就有170種被認(rèn)為處于危險(xiǎn)當(dāng)中。

為什么人們應(yīng)該感到擔(dān)憂呢?因?yàn)槲覀冃枰獎(jiǎng)游?，因?yàn)樗鼈円坏┫В陀肋h(yuǎn)不會(huì)再出現(xiàn)。動(dòng)物不僅僅是漂亮或有趣。它們不僅僅是人類的食物來(lái)源。在維持自然平衡中，每種動(dòng)物都有其作用。毀滅某種動(dòng)物會(huì)導(dǎo)致許多問(wèn)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(cāng)庫(kù)就會(huì)受到老鼠和田鼠的破壞。 為什么?因?yàn)辁棾允箢悾瑳](méi)有鷹控制它們的數(shù)量，鼠類就會(huì)迅速繁殖。

幸運(yùn)的是，有些人正在努力幫助拯救這些動(dòng)物。有些組織籌錢以便人們了解這一問(wèn)題。他們也努力使政府通過(guò)保護(hù)瀕危動(dòng)物的法律。很多國(guó)家已經(jīng)通過(guò)了法律。這些法

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