CNN News:佛罗里达国家沼泽公园生物系统出现混乱

Because they`re not poisonous, a lot of people keep pythons or boa constrictors as pets. But they`re not welcome everywhere. Burmese pythons, for one thing, are huge. They`re among the largest snakes on earth. They can get up to 23 feet long. They can weigh up to 200 pounds.

由于一些蟒蛇或者大蟒蛇是没有毒的，所以许多人把他们当做宠物来养。但是这些大家伙不是在每个地方都受欢迎的。缅甸蟒蛇最大的特点就是大，在世界级巨型蟒蛇中占有一席位置。这种蟒蛇长度可达到23英寸长，重量可达200镑重。

The question you might be asking is what does something that big eat? The answer, you might already know, is a lot, especially based on this next report from John Zarrella. In one part of Florida, the fact that they eat so much is what is becoming the real problem.

你可能要问我他们这么巨大要吃什么?可能大家也都知道答案，他们吃的很多，在看了下面这则来自John Zarrella发回的报道你就知道他们吃什么了。在佛罗里达的一个地方，这些大家伙们的伙食真成了令人头疼的问题。

Florida`s Everglades, home to an incredible cluster of species. But some are disappearing and disappearing quickly.

佛罗里达州的大沼泽地是很多稀奇物种的集合地，但是他们其中一些已经消失或者正在迅速消失。

Raccoons were such a problem that we actually had to put a policy in place to try and manage them.

浣熊是我们首先要解决的问题，我们需要为它们单独出条政策来管理它们。

No policy needed now. Scientists believe this invader to the Everglades, the Burmese python, is responsible for nearly wiping out several species. For eight years, researchers drove back and forth over two main roads in Everglades National Park. They compared the number of dead animals they found -- road kill -- to the numbers recorded in past decades.

现在没有出台政策的必要。科学家坚信这种沼泽地克星，缅甸蟒蛇会将好几种生物驱逐出去。8年的研究中，科学家来来回回往返于沼泽公园两条主要道路上，比较了过去几年与现在动物道路死亡数量。

In areas inhabited by pythons the longest, the findings were stunning. Rabbits and foxes gone. Raccoons and opossums down 99 percent.

发现在蟒蛇出没地区结果令人震惊，该地区兔子和狐狸都消失了，浣熊数量下降了99%。

If a bobcat is looking for something to eat, those are no longer available. What does a bobcat do now?

如果一个蟒蛇想吃东西这些东西远远是不够的，那么它将如何做呢?

And scientists worry what will the snakes eat next? Even more frightening, these non-venomous constrictor snakes may be here to stay. No way to get rid of them all.

科学家担心它们还将会吃什么?虽然害怕，但是这些大蟒蛇可能还要继续留在这里。没有办法将他们移走。

No example we can turn to that they`ve ever been eradicated by any of the tools and techniques we have.

没有前例证实以我们现在的工具和技术可以根除这些大家伙。

It`s a problem that has frustrated park biologist Skip Snow for years. Poison would kill native creatures, too. Traps would catch others besides pythons. And visually hunting them down across a million-plus acres, next to impossible.

这个问题已经困扰蟒蛇专家Skip Snow好多年了，采用毒药同样会伤害到当地生物，设置陷阱其他蟒蛇也可能会被逮到，很明显人力去逮捕根本不可能。

Here`s one of the problems with trying to completely eradicate the python. You probably don`t even see it. It`s right here, a six-footer. Now you could walk up on this snake, and you wouldn`t even know it`s sitting there.

现在还存在一个问题，你可能没有发现。就在这，一个六英尺长的东西，现在你可能都已经踩在蟒蛇身上了而你却没有察觉。

There may be as many as 100,000 pythons slithering through the `Glades. The perception that they are everywhere, rangers say, is flat out wrong. But it is a perception not lost on park visitors.

这里可能有100,000条蟒蛇穿行在沼泽地里，他们无处不在。公园管理者说，它们来错了地方。现在感觉还不会影响到游客数量。

And I says I don`t even know if I want to stop here, because I was afraid that there would be snakes everywhere, pythons and everything.

我甚至不想在这里停留，因为我特别还怕，我知道这里有蛇，有蟒蛇在到处乱跑。

It`s not great mystery how the pythons got here. People bought these exotic pets, and when they got too big, they got rid of them. No one would have guessed, just a decade ago, snakes in this river of grass might upset the balance of nature here forever -- John Zarrella, CNN, Everglades National Park.

蟒蛇为什么出现在这里确实不是很难理解。人们把这种来自异国他乡的生物当宠物来养，当它们长大了之后就将它们丢弃。没人会想到，十年前蛇在这条河里会破坏大自然平衡。John Zarrella在沼泽公园为您报道。
