Oceans Face Mass Extinctions

The oceans are in far worse shape than we thought. In a preliminary report presented to the United Nations, an international team of renowned scientists warned Tuesday that a mass extinction of ocean life would be inevitable if current trends of acidification related to global warming continue. Species from coral to sea turtles could vanish within a generation, and the die-off would rival past extinctions. The situation is “more dire” than any of us thought, the scientists warned.
