研究说酸性化海洋会导致海洋生物减少
Acidic oceans will reduce sea life, says study
Here is the effect of carbon dioxide on sea water.
这就是二氧化碳对海水产生的影响。
These bubbles contain natural CO2 from an underwater volcano in Papua New Guinea.
这些气泡中含有巴布亚新几内亚的一座海底火山所产生的天然二氧化碳。
Few sea creatures can live here because the CO2 has made nearby water more acidic.
几乎没有海洋生物能在这里得以生存，这是因为二氧化碳使附近的水域酸化。
Swim away from those vents, and what a difference.
如果你游离这些排出二氧化碳的气孔，就会发现海水环境大有不同。
The sea's chemistry returns to normal.
海水的化学性质会变回正常值。
And wonderful reef life can thrive.
礁类生物能够繁盛生长。
But industrial society is churning out CO2 on a massive scale.And the gas is being absorbed into seawater round the world, making it all more acidic.
但工业社会正在大规模且快速地产出二氧化碳，而废气则被世界各处的海水所吸收，导致海洋酸化愈发严重。
This comprehensive study confirms what we have been observing globally.
这项综合性研究证实了已在全球范围内被观察到的现象。
Ocean suffocation is a problem.
因海水脱氧而造成的“海洋窒息”是一个急需解决的问题。
Acidity is increasing, and that's not just having an impact on the ecology which we're seeing already.
我们已经看到，日益升高的海水酸度影响到了生态环境。
But it will have an impact on us as humans further down the line.
但除此之外，在未来，它还会波及人类自身。
Take one fish we love to eat, cod. The research shows that baby cod are especially sensitive to more acidic water.
就拿我们爱吃的鳕鱼来打个比方吧。该研究显示，鳕鱼幼崽对酸性更高的水体格外敏感。
It projects that if CO2 levels rise unchecked, we should expect only a quarter as many cod in the seas.
据推测，如果持续升高的二氧化碳水平得不到遏制，未来鳕鱼的数量将减至目前的四分之一。
Some species will thrive with the changes, the scientists say, like some seaweeds.
科学家们说，有些海洋物种并不会受到这一变化的影响，仍会茂盛地生长，比如海藻。
But the report warns that all sea life will be affected by the disruption of the food web in the seas.
但该报告提醒人们，一旦海洋食物网遭到破坏，所有海洋生物都会受到影响。
