海水都变成淡水会发生什么

What if Seawater becomes Freshwater? | #aumsum

It’s AumSum Time.
这里是《奥萨小课堂》时间
What if all the Seawater Becomes Freshwater?
如果海水都变成淡水会发生什么?
Nooo.

What if all the seawater becomes chocolate milkshake?
如果海水都变成巧克力奶昔呢?
Ohh listen.
诶听着
First of all, the biggest advantage will be that.
首先 最大的好处是
It will solve the water crisis all over the world.
它能解决全球的水资源危机
However, there will be quite a number of disadvantages.
然而 也有很多不利之处
Firstly, most of the fishes will die.
首先 大部分鱼会死亡
Why?
为什么?
In freshwater, due to a process called osmosis.
在淡水中 由于一种叫做渗透的过程
The cells of the fishes will swell up, thus eventually killing them.
鱼的细胞会膨胀 最终置它们于死地
Secondly, experts believe that tiny organisms.
其次 专家认为
Called zooplankton and phytoplankton which are critical
在海洋生物食物链中起重要作用的微生物
to the marine life food chain, will die off.
也就是浮游动物和浮游植物 将会因此死亡
Leading to mass extinction of marine life.
导致海洋生物的大规模灭绝
In addition to this.
除此之外
Phytoplankton produce half of the world’s oxygen via photosynthesis.
浮游植物通过光合作用能产生世界上一半的氧气
Without them, there will be far less oxygen available for us to breathe.
没有它们 可供我们呼吸的氧气就会少得多
Lastly, experts believe that salt in the seawater.
最后 专家认为海水中的盐分
Has a major impact on ocean currents which in turn influence our climate.
对洋流有很大影响 而洋流又反过来影响我们的气候
However, as more research is required.
然而 因为还需要更深入的研究
Experts don’t exactly know what will happen
专家并不确切知道
If all the seawater becomes freshwater.
如果所有的海水都变成淡水究竟会发生什么
What if we drink only seawater?
如果我们只喝海水会怎么样?
No, I only drink chocolate milkshake.
不 我只喝巧克力奶昔
Oh, Aumsum.
噢 奥萨
On an average seawater as salinity of about 3.5%
海水盐度的平均值为百分之3.5
When we drink seawater,
当我们喝海水的时候
Water as well as excess salts get absorbed in our blood.
水以及多余的盐份会被我们的血液吸收
One of the functions of our kidneys is to remove this excess salt from our blood.
我们肾脏的其中一个功能就是将血液中多余的盐份排出体外
But urine produced by kidneys
但是肾脏产生的尿液
has a salt concentration which is less than 3.5% of that of seawater.
它的盐浓度少于海水的盐浓度3.5%
Hence needs more water to remove all the excess salt.
因此 需要更多的水来去除多余的全部盐份
As a result, we feel thirsty after drinking seawater.
因此 我们喝了海水后会感到口渴
Excess seawater consumption can lead to dehydration.
过量饮用海水会导致脱水
Secondly, excess drinking of seawater
其次 过量饮用海水
Will also hinder the blood purifying process of our kidneys.
还将阻碍肾脏的血液净化过程
How? Because solute concentration inside the filtering units of our kidneys
如何阻碍?因为我们肾脏过滤单元中的溶质浓度
Will be lower than that of the highly saline blood.
会低于高盐血液中的溶质浓度
Hence, do not osmosis,
因此 无法渗透
Blood doesn’t get purified.
血液无法净化
What if we drink too much water?
如果我们水喝多了怎么办?
Water is super cool.
水超级凉爽
Drink as much as you wish.
你想喝多少就喝多少
Wrong, Aumsum.
错了 奥萨
Drink too much water is not the problem
喝太多水没有问题
but drinking too much water in a short span of time is.
但在短时间内喝太多水才是问题所在
If we drink water beyond the processing capability of our kidneys,
如果我们喝的水超出了肾脏的处理能力
Then they are not able to eliminate the excess water.
他们就会无法排解出多余的水分
As a result, water level increases in our blood and sodium level goes down.
会导致我们血液中的水含量增加而钠含量下降
This condition is known as hyponatremia or water intoxication.
这种情况被称为低钠血症或水中毒
Sodium is an essential electrolyte which balances fluids inside and outside ourselves.
钠是一种必须的电解质 可以平衡我们体内外的液体
The imbalance caused by water level going up
水含量上升造成的不平衡
And sodium level going down causes the fluids outside our cells to move inside.
和钠含量下降导致的细胞外的液体向内移动
As a result, our cells begin to swell,
这样的结果是 我们的细胞开始肿胀
This swelling can cause multiple health problems.
这种肿胀会引起多种健康问题
Also if swelling takes place in our brain cells,
同样如果我们的脑细胞发生肿胀
Then we can get headaches or nausea.
那我们会感到头痛或恶心
This condition can also prove to be fatal.
这种情况被认为是致命的
What if we stopped drinking water?
如果我们不再喝水会怎么样?
We will have to sell our water purifiers to scrap dealers.
我们得把净水器卖给废品经销商
Ah, you are unbelievable.
啊 你真不可思议
About 60% to 80% human body is water.
人体中大约60%至80%是水
We need water for various purposes like digestion and excretion.
我们需要水出于各种目的 例如消化和排泄
Water is also a major component of blood.
水也是血液的主要成分
However, everyday we lose about 2 to 3 liters of water through sweat, urine, breathing etc.
但是 每天我们通过汗液 尿液 呼吸等会损失约2至3升水
Hence, to compensate the water loss,
因此 为了抵消水的损失
If we don’t drink enough water, then we will get dehydrated.
如果我们喝的水不够 那我们就会脱水
During dehydration, our brain works harder than normal
在脱水期间 我们的大脑会比平时更努力地运作
It informs kidneys to retain moisture,
它通知肾脏保持水分
That producing darker concentrated urine.
从而产生浓缩的深色尿液
It reduces the production of saliva causing dry mouth.
它会减少唾液的产生 从而引起口干
Lack of water also causes our brain tissues to shrink.
缺水还会导致我们的大脑组织萎缩
We get headaches and feel nauseous.
我们会感到头痛和恶心
Our energy levels drop and our skin becomes dry.
我们的精力下降 皮肤变得干燥
Besides this, chronic dehydration can lead to severe health problems and even death.
除此之外 长期脱水会导致严重的健康问题 甚至死亡
What if we replace water by soft drinks?
如果我们用软饮料代替水会怎么样?
No,

We should replace salads by burgers and french fries.
我们应该把沙拉换成汉堡和炸薯条
Oh, Aumsum.
噢 奥萨
If we replace our 8 daily glasses of water with 8 soft drinks,
如果我们把每天的8杯水换成8杯软饮料
Then we would be in a big trouble.
那我们就有大麻烦了

过量食用可能引起腹泻
Many soft drinks contain caffeine.
许多软饮料中含有咖啡因
Overconsumption of caffeine can lead to loss of potassium via urine.
过量摄入咖啡因会导致钾元素通过尿液流失
Flow of potassium regulates our heartbeat.
而钾的流动能调节我们的心跳
Low potassium levels may lead to heart palpitations or irregular heartbeat.
钾含量低可能会导致心悸或心律不齐
Overconsumption of caffeine can also lead to insomnia.
过量摄入咖啡因也会导致失眠
She might start staring more its stars instead of sleeping.
