Starfish? The reality this unfortunate headline obscures is that all complex marine life is now circling the drain. The global ocean is dying before our eyes.
Our collective failure to grasp the full scope of what humanity is doing is partially due to the nature of scientific studies, which generally take a piecemeal approach to ecological threats. It's the confluence of multiple threats which confronts marine organisms: warming, acidification, toxic and radioactive pollution, sea level rise, eutrophication (overabundance of nitrogen from fertilizer runoff), deafening military and industrial sonar, overfishing (i.e. fishing), invasive species... it's difficult to compile a comprehensive list. Several of these could be enough alone to kill the global ocean in decades. The combination virtually guarantees a marine extinction event outstripping the worst in Earth's history, in a matter of years.
For those who perceive no intrinsic value in lifeforms which have taken hundreds of millions of years to evolve before getting snuffed out by the human catastrophe, it bears mentioning that dead, stagnant oceans give rise to blooms of anoxic bacteria which have, in the past, emitted enough hydrogen sulfide gas to poison most terrestrial species, including us.
