first victims – coral reefs and oysters

A recent report in Science magazine finds that the oceans are turning acidic at what may be the fastest pace in 300 million years, with potential severe consequences for marine ecosystems.

Among the first victims of ocean warming and acidification are coral reefs, because corals can form only within a narrow range of temperature and acidity of seawater. Oyster hatcheries are also affected, and have been referred to as “canaries in a coal mine” since they may predict effects on a wide range of ocean ecosystems as ocean acidification increases.
