Ocean acidification and impacts on marine life

Rising carbon dioxide emissions are increasing the acidity of the oceans, and scientists have found that some marine animals may not be able to survive the increasingly hostile marine environment.

Scientists in Sweden found that larvae of brittlestars, a relative of starfish found around Europe’s coast, could not develop in laboratory conditions that mimicked the ocean acidity expected in next few decades. The threat to this one species would have wider impacts on the other marine life with which it interacts, and is a more reason, the author proposes, for urgent action to reduce emissions.
