进化的地球（2023）

She manages to lose the raiders in the colony.
[大喊大叫]
[squawking and cheeping]
最后，她可以养活自己的小鸡了
Finally, she can feed her own chick.
尽管有些种类的企鹅需要浮冰
Though some species of penguin need ice floes
为了筑巢，巴布亚人更喜欢在裸♥露♥的土地上摇晃，
to nest, gentoos prefer to rock it out on bare earth,
南极有1500亿吨♥冰融化，
and with 150 billion tons of ice melting in Antarctica,
他们有大量的房♥地♥产♥可供出♥售♥
they've got plenty of real estate to roll with.
是什么让企鹅成为重要的信使
What makes the penguins important messengers
海洋环境的变化
of the changing ocean environment
不仅仅是殖民地的不断扩大
is not just the growing size of the colonies
还有它们的外观
but also how they look.
[尖叫]
[squawking]
线索写在地上
The clues are written on the ground
在dookie
in dookie.
我的意思是，我和每个人一样热爱大自然，
I mean, I love nature just as much as everybody,
可能比大多数人都多，
probably more than most,
这仍然很难理解
and that's still hard to look at.
它就像一把水枪
It's like a water gun.
这只企鹅粪便的颜色可以告诉我们很多
The color of this penguin poop can tell us a lot.
巴布亚人应该吃磷虾，
The gentoos should be eating krill,
让他们的便便变成粉红色，
making their poop pink,
但磷虾需要海冰才能繁殖...
but krill need sea ice to breed...
这里再也没有什么可去的了，
and there ain't much of that to go around here anymore,
所以这里的便便都是...
so the poop here is all...
白色
white...
因为这些气候变化的赢家
because these climate change winners
正在适应捕猎鱼类和鱿鱼
are adapting to hunt fish and squid instead.
他们的成功被涂上了一大堆粪便，
Their success painted with over a ton of poop,
污渍太大了，可以从太空追踪到
stains so big, they can be tracked from space.
研究人员现在正在使用卫星图像
Researchers are now using satellite images
追踪企鹅种群
to track penguin populations
以及他们周围的海洋状况
and the state of the ocean around them.
用这种方式检查卫星
Checking the satellites in this way
把便便侦探带到了一个巨大的粉红色污渍...
led the poop detectives to a massive pink stain...
这标志着一个由近一百万只企鹅组成的庞大群体
signaling a huge colony of almost a million penguins.
[尖叫]
[squawking]
不是贵族，而是他们的表亲阿德利
Not gentoos, but their cousins, Adélies.
Adélies需要冰才能生存
Adélies need ice to survive.
近年来，随着海冰的消退，
With sea ice retreating in recent years,
科学家们记录了整个殖民地的灭绝，
scientists have recorded extinctions of entire colonies,
但在这里，他们正在蓬勃发展，
but here, they're thriving,
粉红色表明有很多
and the pink color shows there are plenty
周围的喜冰磷虾供它们食用
of ice-loving krill around for them to feed on.
事实上，这里的冰盖正在增长，而不是缩小
In fact, the ice sheet here is growing, not shrinking.
这种气候变化是反过来的吗？
Is this climate change in reverse?
科学家们一直在努力解决
Scientists have been working to solve
这个南极之谜持续了10多年
this Antarctic riddle for over 10 years.
它甚至被否认气候变化的人所采用
It's even been adopted by climate change deniers.
那到底是怎么回事？
So what the hell is going on?
好吧，你得等着看
Well, you're gonna have to wait to find out
因为首先，我想带你去
because first, I want to take you
在另一种动物的旅程中
on a journey of another animal
这个星球上最伟大的爱情故事之一...
with one of the greatest love stories on the planet...
紧随其后的是Sally Poncet
followed by Sally Poncet, who has spent
一生研究这些鸟的私生活
a lifetime studying the private lives of these birds.
之前有三四个流浪者，
[Sally] There were 3 or 4 wanderers earlier,
但它们只是暂时消失了，
but they've just disappeared for the moment,
但是所有这些——哈哈哈！他们来了
but all these--ha ha ha! Here they come.
她一直在追踪健康状况
[Shane] She's been tracking the health
流浪信天翁30多年
of the wandering albatrosses for over 30 years.
我开始数那些信天翁
[Sally] I started counting the wandering albatross
几十年前
many, many decades ago.
真的很感激萨莉的关系
[Shane] To really appreciate Sally's relationship
有了这些鸟，我们需要把时钟倒回去一点
with these birds, we need to rewind the clock a little.
啊，说来话长 呵呵
Ah, very long story. Heh heh.
她第一次访问南极时只有21岁
[Shane] She was only 21 when she first visited the Antarctic.
我第一次来这里是在一艘帆船上
[Sally] I first came here on a sailing boat.
我们的计划是去南极半岛，
Our plan was to go to the Antarctic Peninsula,
在那里度过一个冬天
spend a winter there.
这是我们的计划，但很意外
[Shane] That was the plan, but a surprise
是一个婴儿来到这里
was the arrival of a baby out here.
我们的第一个孩子出生在南乔治亚州，
[Sally] Our first child was born in South Georgia,
我们又生了两个孩子
and we had two more children.
他们在船上长大
They grew up on the boat.
是的，对他们来说，这真的是美好的童年回忆
Yeah, for them they're really good childhood memories.
莎莉和三个孩子住在船上
[Shane] Sally was living on a boat with 3 kids
在地球上最危险的海洋之一
in one of the most dangerous oceans on the planet.
南乔治亚的小岛，
The tiny island of South Georgia,
距离南美洲海岸一千多英里，
over a thousand miles off the coast of South America,
是她为数不多踏上旱地的地方之一
was one of the few places she set foot on dry land.
我们每年夏天都去南乔治亚州，
[Sally] We went to South Georgia every summer,
我只是对这些鸟很感兴趣
and I was just really interested in the birds
在这个地方，我开始数
in this place, and I started counting them.
从那以后她每年都回来，
[Shane] And she's returned every year since,
尽管这些天她在一艘更令人印象深刻的船上
although these days she's on a much more impressive boat.
她不会停止登记的
She's not gonna stop checking in
很快就会对这群人产生影响
on this population anytime soon.
我仍然希望能够理解
I still want to be able to understand
它是如何工作的
how it works.
我还没弄清楚
I haven't quite figured it out.
这些年来，我一直能够回来
Over the years, I've been able to return
每年夏天，并继续这些计数
every summer and-—-and continue those counts.
我已经建立了一个长♥期♥发生的事情的图景
I've built up a picture of what's happening long term.
这就是爱情故事的由来
[Shane] This is where the love story comes in.
[信天翁咕哝]
[albatrosses grunting]
[低沉的颤音]
[low trilling]
这可能是个开始
[Sally] This could be the beginning
终身伴侣
of a life-long pairing.
信天翁终身伴侣
[Shane] Albatross mate for life
通常只有其中一人在海上死亡时才会分开
and usually only split if one of them dies at sea.
他们可以在一起长达50年
They can spend up to 50 years together.
我真的无法想象
[Sally] I can't really imagine anything
比你在这里看到的更亲密
more intimate than what you can see here.
并不是说他们没有奇怪的婚姻争吵
[Shane] Not that they don't have the odd marital tiff.
[喋喋不休]
[chattering]
他真的不高兴 哈哈！
He's really not happy. Ha ha!
告诉他继续前进
Telling-- uh, telling him to move on.
[信天翁尖叫]
[albatross screeching]
哇！
Wow!
你只是花点时间看看他们在做什么
You just take the time to see what they're doing
而不是匆匆忙忙地数数
instead of rushing round and counting.
太棒了
It's just wonderful.
你也有这样的时刻
You have these moments just like this one here.
只是非常平静
Just very peaceful.
我们都在关注趋势，并努力
We're all looking at the trends and trying to
弄清楚是什么让种群保持稳定
figure out what it is that makes the populations stay stable.
我们现在还没有完成计数，
We haven't finished the counts at the moment,
我们再过一个小时左右就会知道
so we'll know that in another hour or so.
我必须站起来，重新开始数数
I've got to get up and start counting again to do that.
我们最好让萨莉继续干下去
[Shane] We better let Sally get on with it.
信天翁正在安装GPS追踪器
The albatrosses are getting fitted with GPS trackers.
[喋喋不休]
[chattering]
想到这些鸟可能很容易
It might be easy to think of these birds
就像大海鸥一样，但当你靠近时，
as big seagulls, but then you get close,
而且，伙计，它们是巨大的吗
and, man, are they huge.
嘘
Shh.
好的，伙计 好啊
OK, buddy. OK.
嘘！嘘！
Shh! Shh!
我知道
I know.
他们交换了这只雌性的卵子
[Shane] They swap out this female's egg
作为诱饵，这样它就不会在这个过程中受损
