CNN News:佛羅里達(dá)國家沼澤公園生物系統(tǒng)出現(xiàn)混亂

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沒有毒的，所以許多人把他們當(dāng)做寵物來養(yǎng)。但是這些大家伙不是在每個地方都受歡迎的。緬甸蟒蛇最大的特點(diǎn)就是大，在世界級巨型蟒蛇中占有一席位置。這種蟒蛇長度可達(dá)到23英寸長，重量可達(dá)200鎊重。

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.

你可能要問我他們這么巨大要吃什么?可能大家也都知道答案，他們吃的很多，在看了下面這則來自John Zarrella發(fā)回的報(bào)道你就知道他們吃什么了。在佛羅里達(dá)的一個地方，這些大家伙們的伙食真成了令人頭疼的問題。

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

佛羅里達(dá)州的大沼澤地是很多稀奇物種的集合地，但是他們其中一些已經(jīng)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.

浣熊是我們首先要解決的問題，我們需要為它們單獨(dú)出條政策來管理它們。

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.

現(xiàn)在沒有出臺政策的必要。科學(xué)家堅(jiān)信這種沼澤地克星，緬甸蟒蛇會將好幾種生物驅(qū)逐出去。8年的研究中，科學(xué)家來來回回往返于沼澤公園兩條主要道路上，比較了過去幾年與現(xiàn)在動物道路死亡數(shù)量。

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

發(fā)現(xiàn)在蟒蛇出沒地區(qū)結(jié)果令人震驚，該地區(qū)兔子和狐貍都消失了，浣熊數(shù)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?

如果一個蟒蛇想吃東西這些東西遠(yuǎn)遠(yuǎn)是不夠的，那么它將如何做呢?

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.

科學(xué)家擔(dān)心它們還將會吃什么?雖然害怕，但是這些大蟒蛇可能還要繼續(xù)留在這里。沒有辦法將他們移走。

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

沒有前例證實(shí)以我們現(xiàn)在的工具和技術(shù)可以根除這些大家伙。

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.

這個問題已經(jīng)困擾蟒蛇專家Skip Snow好多年了，采用毒藥同樣會傷害到當(dāng)?shù)厣?，設(shè)置陷阱其他蟒蛇也可能會被逮到，很明顯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.

現(xiàn)在還存在一個問題，你可能沒有發(fā)現(xiàn)。就在這，一個六英尺長的東西，現(xiàn)在你可能都已經(jīng)踩在蟒蛇身上了而你卻沒有察覺。

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.

這里可能有100,000條蟒蛇穿行在沼澤地里，他們無處不在。公園管理者說，它們來錯了地方?，F(xiàn)在感覺還不會影響到游客數(shù)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.

我甚至不想在這里停留，因?yàn)槲姨貏e還怕，我知道這里有蛇，有蟒蛇在到處亂跑。

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.

蟒蛇為什么出現(xiàn)在這里確實(shí)不是很難理解。人們把這種來自異國他鄉(xiāng)的生物當(dāng)寵物來養(yǎng)，當(dāng)它們長大了之后就將它們丟棄。沒人會想到，十年前蛇在這條河里會破壞大自然平衡。John Zarrella在沼澤公園為您報(bào)道。
