marine species facing 'unprecedented threats'

...it turns out that even the fathomless depths of the oceans have limits. The U.N. reports that 32% of global fish stocks are overexploited or depleted and as much as 90% of large species like tuna and marlin have been fished out in the past half-century. Once-plentiful species like Atlantic cod have been fished to near oblivion, and delicacies like bluefin tuna are on an arc toward extinction. A recent report by the International Programme on the State of the Ocean found that the world's marine species faced threats "unprecedented in human history" — and overfishing is part of the problem.
