A study published in May 2017 tells us that oxygen is depleting in the oceans two or three times faster than expected.

From Think Progress:

    by combining oxygen loss with ever-worsening ocean warming and acidification, humans are re-creating the conditions that led to the worst-ever extinction, which killed over 90 percent of marine life 252 million years ago.
