如果南极洲是雨林会怎样?

What If Antarctica Were a Rainforest?

About 90 million years ago,
大约九千万年前
the frozen realm of Antarctica
冰天雪地的南极洲
used to be a lush, swampy, temperate forest,
曾是一片繁茂松软 气候温和的沼泽森林
similar to those found in New Zealand today.
与现在于新西兰发现的森林相似
The rainforest managed to thrive,
即使在有四个月极夜
even with four months of polar night,
没有阳光的情况下
when there was no sunlight.
雨林依然茁壮生长
What if this ancient rainforest
假如 这片古老的森林
decided it was time to make a comeback?
觉得是时候卷土重来 将会怎样?
What if Antarctica became a rainforest?
假如南极洲变成了雨林 将会怎样?
Would this work out well for us?
这会对我们有什么好处吗?
Or be devastated for the human race?
还是说会毁灭人类呢?
This is WHAT IF
这里是“WHAT IF”节目
a history would happen
如果南极洲是一片雨林
if Antarctica were a rainforest.
可能会发生的事情
Rainforests are the oldest living ecosystems on land,
雨林是大陆上最古老的生态系统
and there is complex as they are diverse.
它们既复杂又多样化
They’re home to over half of the planet’s plant and animal species
它是地球上超过一半动植物的家园
while only covering 6% of the Earth’s surface.
但却只占了地球表面积的6%
Just 10 km² of rainforest
只有10平方公里大小的雨林
can contain up to 1,500 flowering plants,
就可以容纳多达1500种开花植物
750 different species of trees,
750种不同的树
400 species of birds,
400种鸟类
and 150 species of butterflies.
以及150种蝴蝶
Antarctica has an area of 14 million km²
南极洲占地1400km²
which makes it about 1.4 times bigger than Europe,
这代表它是欧洲的1.4倍大
and almost twice the size of Australia.
而且几乎是澳大利亚的两倍大
Now, imagine all that frozen tundra
现在 想象一下所有的南极冻土
was lush with plant and animal life.
到处充满了的动植物
If Antarctica was a rainforest,
如果南极洲是一片雨林
it could consume more
那么它就可以消耗
of the world’s carbon dioxide,
地球上更多的二氧化碳
reducing the amount in the atmosphere.
减少大气中的二氧化碳含量
That could be very helpful
这会非常有利于
in our fight against climate change.
我们与气候变化作斗争
There could be new resources for us to exploit,
那里可能会有新资源供我们开发
such as plants for medicines and food,
例如可药用或食用的植物
more trees for buildings and fancy furniture.
很多可用于建筑及高档家具的树木
Awesome, right?
很棒 对吧?
But there is a downside.
但是这也不好的一面
Before we would be able to exploit these new resources,
在我们可以开发 这些新资源之前
we would need to increase the carbon dioxide in the atmosphere.
我们需要增加大气中的二氧化碳
Carbon dioxide helps to heat the Earth’s atmosphere.
二氧化碳会加快 地球的大气变暖进度
The current levels of atmospheric carbon dioxide
目前大气中二氧化碳的含量
won’t be able to support a massive temperate rainforest in Antarctica.
让南极洲变成大片的温带雨林
But as we know,
但是我们都知道
increasing carbon dioxide is a bad idea.
增加二氧化碳是个糟糕的办法
It would be extremely harmful
这会是非常有害的
and only add fuel to the fire that is climate change.
这只会是在气候变化上 火上浇油
And with Antarctica going through its green makeover,
随着南极洲进行它的绿色改造
massive amounts of ice would melt.
大量的冰将会融化
This means there would be a less white area to reflect sunlight,
这意味着能反射阳光的白色区域将减少
and more dark area to absorb warmth.
而吸收热量的黑色区域将增加
That would accelerate climate change
这将加速气候变化
to the point that the Earth wouldn’t even be hospitable for us.
甚至让地球变得不适合我们居住
But would the carbon dioxide consumed by the new rainforest
但是 新雨林消耗的二氧化碳
balance out the increased warming?
能否抵消全球变暖的影响呢?
Well, here’s the problem.
这 就是问题所在
We don’t know.
我们不知道
Current studies haven’t been able to come up with an answer to this question.
目前的研究还不能得到这个问题的答案
So, you feel lucky?
那么 你觉得幸运?
Well, do you?
你会这样觉得吗?
The loss of ice would also impact
冰川的消失也会影响到
the species that currently inhabit that area.
目前居住在这一地区的物种
Oh no, not the penguins!
哦 不 不要是企鹅!
And to make matters worse,
更糟糕的是
ice doesn’t just disappear,
冰不会凭空消失
It melts.
它会融化
All that water would have to go somewhere.
所有的水都要流向某个地方
The Antarctic and Southern Ocean Coalition
南极和南大洋联盟预估
estimates that sea levels would rise at least 60 m (200 ft).
海平面将上升至少60米(200英尺)
Florida,
佛罗里达
the Amazon river basin,
亚马逊河流域
and Central China,
和中国中部
they’d all be underwater.
它们都将沉入水中
Between one and two billion people would be displaced.
大约有10亿到20亿人将会流离失所
That is, unless they want to go the way of Atlantis.
除非他们想重蹈亚特兰蒂斯的覆辙
Well, it can’t get any worse, can it?
不能再糟了 对吧?
Uh

Our ocean currents would be disrupted by the influx of water.
我们的洋流会因水的涌入而中断
So what does all this mean for you?
那么 这一切对你来说意味着什么呢?
Well, the changing ocean currents could
洋流的变化可能会
seriously mess up the Earth’s weather patterns.
严重扰乱地球的气候模式
Agricultural land that we depend on for food could be turned into deserts.
我们赖以生存的农田可能会变成沙漠
Deserts could be turned into flooded plains.
沙漠可能变成洪水泛滥的平原
“dogs and cats, living together, mass hysteria!”
“简直就如猫狗同住 混乱不堪!”
“Enough, I get the point!”
“够了 我明白你的意思了!”
We can only guess where these changes might occur
由于地球天气系统的复杂性
because of how complex the Earth’s weather system is.
我们只能猜测这些变化可能发生在哪里
So, could Antarctica turn into a rainforest?
那么 南极洲会变成热带雨林吗?
Well, it’s already starting to happen.
其实这已经开始了
Climate change is currently turning Antarctica green.
气候变化正在使南极洲变绿
If we don’t curb our greenhouse gas emissions,
如果我们不控制温室气体的排放
our planet is going to continue to heat up,
我们的地球将继续升温
and ice is going to continue to melt.
冰川将继续融化
It is possible that eventually,
可能 最后
we could turn Antarctica into a green continent.
我们会把南极洲变成一个绿色的大陆
But it may lead to devastating consequences for our survival.
但它可能会给我们的生存带来毁灭性的后果
And if Antarctica did become a rainforest,
如果南极洲真的变成了雨林
that would mean a lot of uncharted territory to explore.
这意味着有很多未知领域需要探索
In the Amazon Rainforest alone,
仅仅在亚马孙雨林
a new species is discovered every other day.
每隔一天就会发现一个新物种
What could be hiding in a new Antarctic rainforest?
在一个新的南极州雨林里又隐藏着什么呢?
Could we finally find some long lost creatures,
我们最终能否找到一些失踪已久的生物
like Bigfoot?
比如大脚怪?
Well, that’s a story for another WHAT IF.
好吧 这又是另一个“WHAT IF”的故事
