The problem is that today we're pumping out somuch carbon dioxide

问题是今天我们往大气层输入的二氧化碳太多了

that the ocean just can't keep up.

海洋已经跟不上了

As a result, they're turning acidic faster than theyhave for millions of years.

结果，它们的酸化速度 超过过去几百万年

Some estimate that every year, two billion tons of carbon dioxide are absorbed by the oceans.

The first creatures that will suffer will be the coral that make up the world's great reefs.

第一个受难的生物 就是组成世界巨大暗礁、的珊瑚

Their skeletons can't form if the water becomes too acidic.

如果水酸性太大它们就无法形成骨骼

If the oceans continue to acidify at their current rate,

如果海洋以目前的速度酸性化

coral could eventually disappear from our oceans.

珊瑚将最终从海洋中消失

With the coral would go all the other life that depends on them.

其它依靠珊瑚存活的生物也会消失

If ocean acidification continues, coral would be just the beginning.

如果海洋酸性化继续珊瑚死亡只是一个开始

Phytoplankton are also vulnerable.

浮游植物也会受到侵害

In the long term,this could endanger one of the main sources of oxygen on the planet.

从长远来看 这会威胁到地球主要供氧源

We are heading into uncharted territory.

这对我们来说还是个未知领域

The truth is scientists don't know

事实上，科学家还不知道

what the full implications of changes on this scale are likely to be.

海洋中的变化对于我们来说意味着什么?

What they do know is that the oceans are fundamental to all life on Earth.

我们只知道 海洋是地球生命的支撑

If the history of the ocean has taught us anything,

海洋的历史能够教会我们的

it's that when the sea is pushed too far, life on Earth suffers.

就是所有生命都要依靠海洋生存

In a battle between humans and the oceans,there will only be one loser.And it won't be theoceans.

人与海洋的战争中 只有一个输家 而那一定不是海洋
