- Ocean acidification
A quick explanation: Since humans began burning fossil fuels, carbon dioxide levels have risen dramatically, and the oceans absorb about a quarter of that carbon dioxide. This excess carbon dioxide that dissolves in the water makes the oceans more acidic. Specifically, the carbon dioxide and the seawater form carbonic acid. The carbonic acid breaks up into hydrogen ions and bicarbonate ions, and it is the extra hydrogen ions that make the water more acidic. These hydrogen ions prevent many organisms–particularly shelled ones, such as oyster or scallops–from being able to take in calcium carbonate to make their shells. When their shells are too thin, many of these organisms have a hard time growing, or they spend so much energy trying to grow their shells that they are unable to spend any energy on growing other parts of their bodies or defending themselves against disease. Ocean acidification is happening so fast that many scientists worry that most organisms can’t adapt to it and that we will lose a great deal of ocean biodiversity.
