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 plant on the danger list. Slowly, the number of some animals in danger is growing.
動物是自然資源,人們浪費了所有通過我們的歷史。動物被殺的毛皮和羽毛,食物,運動,僅僅因為他們的方式。成千上萬種動物已經從這個地球上永遠地消失了。數以百計的今天也在名單之列。約170種僅在美國就有危險。
為什么人們會在意嗎?因為我們需要動物,因為一旦他們消失了,再也不會了。動物不僅僅是漂亮或有趣。他們不僅僅是一種食物。每個動物都有其自然的平衡。毀滅一種動物會產生很多問題。例如,當農民殺死大量的鷹派,農民的玉米和谷物被老鼠和老鼠。為什么?因為鷹吃鼠類,沒有鷹控制它們的數量,鼠類繁殖很快。
幸運的是,有些人正在努力幫助拯救這些動物。一些組織籌錢讓人們了解這一問題。和他們試圖使政府通過保護瀕危動物的法律。很多國家已經通過了法律。這些法律禁止殺害任何動物或植物在危險名單上。慢慢地,某些瀕危動物的數目正在增長。
