海洋酸化为什么特别让珊瑚和贝壳类受害？
Why does ocean acidification especially harm corals and shellfish?
酸化会减少海水中的碳酸根离子，而珊瑚和贝类需要用它来造碳酸钙外壳骨骼；离子变少，它们长壳变难，幼体也更脆弱。
Acidification lowers carbonate ion concentration, which corals and shellfish need to build calcium-carbonate shells and skeletons; with fewer ions, shells form poorly and larvae weaken.

海洋为什么会“变酸”，这和二氧化碳有什么关系？
Why is the ocean becoming more acidic, and what does CO2 have to do with it?
海洋吸收了大量人为排放的二氧化碳，二氧化碳溶于水生成碳酸，使海水 pH 下降、酸度上升，这就是海洋酸化。
The ocean absorbs much of the CO2 humans emit; dissolved CO2 forms carbonic acid, lowering seawater pH and raising acidity—this is ocean acidification.

海水的酸度变大一点，真的会让小鱼小虾受伤吗？
Can a small rise in ocean acidity really hurt little fish and shrimp?
会。酸度升高让许多小生物的外壳变软、长不好，依赖它们为食的鱼虾也会跟着受影响。
Yes. Higher acidity softens and stunts the shells of many small creatures, and the fish and shrimp that eat them are affected too.
