如果地球上再无海洋

What If Earth’s Oceans Evaporated?

[背景乐]
(background music)
如果地球上的海洋都消失了会怎么样?
What if all the oceans disappeared from the Earth’s surface?
没有海洋的世界是什么样的?
What would a world with no high seas look like?
所有海洋生物将何去何从?
What would happen to all the creatures that live under water?
如果世界上没有海洋了
Could humanity survive on the planet
人类还能生存吗?
if there were no oceans left?
这里是《自然无常》
This is What If
今天来讲讲
and here’s what would happen
如果地球上所有海洋都蒸发了 会发生什么
if all the Earth’s oceans evaporated.
早期的地球表面平的
In the early years of our planet, the earth was flat,
但可能不是你想象的那样
but not in a way you might think.
地球上没有任何山川
The earth just didn’t have any mountains
大部分地方都被水覆盖着
and was mostly covered with water.
大约在十亿年前
Then about a billion years ago,
陆地从大海中浮现出来
land emerged from under the sea
地球的大气层环境也发生了改变
and changed the planet’s atmosphere.
于是地球上慢慢开始出现了生命
This led to the debut of the first life-forms here on earth.
可终有一天 地球会越来越暖
Eventually, the planet will heat up
所有的海洋将会消失
and all the oceans will vanish.
但那至少是十亿年后的事了
This isn’t scheduled to happen for another billion years.
假如所有的海洋现在就消失
But how bad would it be
会产生多可怕的影响呢?
if all the oceans evaporated right now?
现在 海洋面积占地球表面的70%
Today, oceans cover about 70% of the Earth’s surface.
如果你把所有海水倒进奥运会规格的游泳池
If you put all that water into Olympic sized swimming pools,
大概能填满500万亿个
you’d need over 500 trillion of them.
海洋消失以后
With all the oceans gone,
我们还剩下一些水
we’d still have some water available.
海水只占地球上水资源总量的97%
Oceans account for 97% of all the water on the planet.
剩余3%的水分布于河流
The remaining 3% is held in rivers,
湖泊 地下水 甚至冰川中
lakes, underground water, even the ice caps.
但这远远无法弥补海洋消失造成的损失
But that wouldn’t be enough to make up for the loss of the oceans.
海洋作为全球气候控制系统
The world’s oceans act as a global climate control system.
它们吸收了大部分来自太阳的热量
They absorb most of the sun’s heat
并把热量平均分布到地球的各个角落
and distribute it evenly around the planet
这样就不会有地方太热或太冷
so that no one area gets too hot or too cold.
海洋还维持水循环
They also sustain the water cycle,
海水蒸发进入大气 再以降雨形式回到地表
evaporating into clouds and then raining back to earth.
一旦世界上的海洋都消失了
But you won’t need to keep your umbrella at hand,
除非大风暴来临 你都不需要拿伞了
expecting a big storm once all the oceans evaporated.
但这种情况下
In our scenario,
地球将无法保持大气层中的水蒸汽含量
the earth wouldn’t be able to keep all that vapour in the atmosphere.
如果海洋永远地消失
Oceans would leave our planet for good,
地球会被烤焦 变成一个大沙漠
turning it into a vast scorching desert.
这种情况下
Sea creatures would be the obvious
显然海洋生物会首当其冲成为受害者
first casualties in these conditions.
要是没有海洋吸收太阳的热量
Then with no oceans to absorb the heat from the Sun,
地球会被慢慢晒干 直到变成金星那样
the earth would slowly roast until it turned into Venus.
距离地球不宜居住还剩下多久?
How long would we have until our planet became uninhabitable?
其实 不论还剩下多少水资源
Well, whatever water was left
都会在几天内被蒸发
would evaporate in a matter of days,
人类也将死于脱水
leaving humanity to die from dehydration.
大多数动物也会因为缺水而灭绝
Most animals would go extinct without water.
谁知道呢?
Who knows?
也许骆驼能成为地球上的幸存者
Maybe camels would become Earth’s next civilization.
再过几天
After a few days,
植物们也会因为缺水而无法生存
plants would give up their attempts to survive without water.
几周后
After a few weeks,
同样的事情还会发生在森林身上
the same would happen to our forests.
最终 森林会着火并不停燃烧
Eventually, they’d catch fire and would keep burning
直到不再剩下一草一木
until there was no vegetation left.
大约一年内
In about a year’s time,
地球就会变成一块烧焦的 无生命的岩石
the earth would turn into a burnt and lifeless Rock.
如果没有水资源
And without water,
或许地球再也没有孕育生命的可能
it probably wouldn’t get the chance to produce life ever again.
也许有一天
Maybe one day,
其他星系的生物造访太阳系时
another life-form might visit our solar system
会好奇曾经如此辉煌的星球发生了什么
and wonder what happened to our once glorious planet.
那就是《自然无常》的另一个故事了
But that’s a story for another What If.
