More environmental gloom and doom:
The ocean is losing its oxygen. Last week, in a sweeping analysis in the journal Science, scientists put it starkly: Over the past 50 years, the volume of the ocean with no oxygen at all has quadrupled, while oxygen-deprived swaths of the open seas have expanded by the size of the European Union. The culprits are familiar: global warming and pollution. Warmer seawater both holds less oxygen and turbocharges the worldwide consumption of oxygen by microorganisms. Meanwhile, agricultural runoff and sewage drives suffocating algae blooms.
The analysis builds on a growing body of research pointing to increasingly sick seas pummeled by the effluent of civilization. In one landmark paper published last year, a research team led by the German oceanographer Sunke Schmidtko quantified for the first time just how much oxygen human civilization has already drained from the oceans. Compiling more than 50 years of disparate data, gathered on research cruises, from floating palaces of ice in the arctic to twilit coral reefs in the South Pacific, Schmidtko’s team calculated that the Earth’s oceans had lost 2 percent of their oxygen since 1960.

Acidification, low oxygen, plastics, global warming - which one will kill our oceans first? Maybe all of them together.
Face it - humanity is killing this planet. And we're not even CLOSE to implementing the sort of changes which will be needed to stop the process.
