1、 No onenot even the governmentcan afford to buy or control all the land that endangered species live on. Good point. In fact, thats what makes the Endangered Species Act difficult to fully enforce. Theres an ongoing conflict between some landowners and the government. Take the case of the gray wolf,

2、 for instance. At one time, the wolves were common all over North America, but by the 1930s they were nearly all killed. Then in 1973, the wolves came under the protection of the Endangered Species Act, along with huge areas of landin Wyoming and Idaho, for example. This angered ranchers. They think

3、 they should have the right to shoot wolves that threaten their sheep and cows. So, landowners may understand the need for the protection of endangered species, but its understandable that they might also feel that the Endangered Species Act violates their rights. Yes? Is the law working? I mean, wh

4、at is the status of endangered species today in the United States? Unfortunately, the situation of threatened and endangered animals is worse now than in 1973, even with the Endangered Species Act in place. Reports on topics such as habitat loss, deforestation, and overfishing show that the situatio

5、n for many species is far worse now than it was in 1973. Let me be more specific. Right now over 1,300 species in the United States are listed as endangered or threatened. And, its important to keep in mind that not many species are ever taken off the list. Since 1973, in fact, only around 39 specie

6、s have been removed from the Endangered Species list. But that number doesnt indicate the complete story. Whats significant about that number is that only 14 species were removed because they had actually recovered. Nine species became extinct, and the others were removed from the list after scienti

7、sts found evidence that listing the species had been a mistake in the first place. Meanwhile, another 300 species may soon be added to the list, including a plant, the Las Vegas buckwheat, and an insect, the Miami blue butterfly. So, you see, even with the Endangered Species Act in place, were not m

8、aking as much progress as we would like. Any more questions? OK, lets move on to the next exhibit. This way, please.导游:好吧,各位,这是我们的下一个展览。你看到小鸟的身体在那瓶吗?这是一个昏暗的海滨麻雀。这是一个老男人死于6月16日,1987年。有点伤心,因为他是世界上最后一个昏暗的海滨雀。他们现在已经灭绝。是的,你有问题吗?男:你知道他们为何绝种了吗?根本上,他们失去了他们的栖息地。看到的,忧郁的海滨麻雀只住在一个地方在佛罗里达州梅里特岛。岛上有很多蚊子和湿地。梅里特岛上的人

9、使用化学物质杀死蚊子。这些化学物质也非常有害的麻雀,和许多死亡。此外,梅里特岛上的人们试图控制和利用湿地。他们改变,湿地不再麻雀的良好栖息地。鸟儿死了一个接一个,直到没有了。女:那么,如果人们指责,我们不能确保这样的事情不会再发生?我们尝试。昏暗的海滨麻雀的情况使一件事非常清楚。我们需要保护濒危动物。但是,它是一个更好的策略来保护动物和他们的栖息地。毕竟,如果动物的栖息地遭到破坏,动物可能会灭绝。这就是为什么?濒危物种法?于1973年传入美国,保护濒危动物和它们的栖息地。例如,虹鳟其生活在河流和小溪美国西海岸的推广的时候,例如在华盛顿州的哥伦比亚河。最近,鱼和河流遭到濒危物种法案的保护。但是我

10、们如何保护河流和森林等大型区域?甚至没有不延伸买得起或控制的所有土地濒危物种生活在。好点。事实上,这就是?很难完全执行。有一个正在进行的一些土地所有者和政府之间的冲突。以灰狼的情况为例。一次,狼是常见的全北美,但到了1930年代他们几乎全部死亡。然后在1973年,狼群受到的保护濒危物种法案,以及巨大的陆地地区怀俄明州,爱达荷州,例如。这激怒了农场主。他们认为他们应该有权开枪狼威胁他们的绵羊和奶牛。那么,土地所有者可能理解需要保护濒危物种,但这是可以理解的,他们也会觉得濒危物种法案违反了他们的权利。是吗?就是法律工作吗?我的意思是,今天是濒危物种的地位在美国?不幸的是,威胁和濒危动物的情况现在比

11、1973年更糟,即使?。报告主题如栖息地的丧失,砍伐森林,过度捕捞表明,许多物种的情况是现在比1973年严重得多。让我更具体。现在在美国超过1300个物种被列为濒危或受威胁。而且,重要的是要记住,并不是许多物种都过了。事实上,自1973年以来,只有大约39物种已经从濒危物种名单中删除。但这一数字并不表示完整的故事。这个数字有什么意义,只有14个物种被移除,因为他们已经恢复。九个物种灭绝,和其他科学家们发现的证据说明,后被从名单中删除清单中的物种是个错误。与此同时,另一个300种可能很快就会被添加到列表中,包括植物、拉斯维加斯荞麦、昆虫,迈阿密蓝蝴蝶。所以,你看,即使?,我们不是我们想让尽可能多

Todays topic is on the pros and cons of legalized hunting. First, Yumi will present arguments in support of hunting. Raoul will respond to

17、her points and present his arguments against hunting. Speakers, are you ready?Raoul: Yes.Yumi: Ready. Yumi, please begin. Thank you. Well, the main argument I want to make today is that hunting contributes to wildlife conservation in a few important ways. First, uh, contrary to what you might think,

18、 hunting actually helps many species survive by controlling their populations. So, for example, without hunting, deer populations would be too large, and many animals would starve because there wouldnt be enough food to sustain them. Thats a good argument, but I think youre ignoring an important poi

19、nt. Another reason deer populations could grow too large is because we have killed off wolves and mountain lions, um, and other animals that used to hunt deer. So, instead of allowing humans to hunt, we should allow populations of meat-eating animals to recover. OK, but dont forget that wolves and m

20、ountain lions dont just eat deer and elk. They also eat sheep and cows, and thats, thats a problem for ranchers. So, this is not a simple issue. Anyway, let me continue with my next point. The second way that hunting supports wildlife conservation is through the sale of stamps. Many hunters have to

21、buy stamps before they can legally hunt birds for instance, ducks and geese. Oh, and when I say stamps, I dont mean the type of stamps you use to mail a letter. The stamps Im talking about are a kind of license to hunt. In the United States, the governments Duck Stamp program raises more than 25 mil

22、lion dollars annually. And a lot of that money is used for protecting and maintaining bird habitats. Since 1934thats when the first stamps were soldthese funds have been used to buy 2.1 million hectares of land for wildlife conservation. So, as you can see, hunters actually help wildlife conservation efforts. Thank you, Yumi. Now lets hear from Rao
