These are the conclusions of a (distinguished) group of marine scientists who met at Oxford University, England, in April to discuss the impact of human activity on the world's oceans.
The meeting, led by the International Programme on the State of the Ocean (IPSO), examined the combined effects of pollution, acidification, (ocean) warming, over-fishing and depleting levels of oxygen in the water.
The panel found that oceanic conditions are (similar)to those of "previous major extinctions of species in Earth's history," and that we face losing marine species and entire marine ecosystems, such as coral reefs, within a single generation.
