More acidic ocean could spell trouble for marine life's earliest stages http://apocadocs.com/s.pl?1217765910
Increasingly acidic conditions in the ocean—brought on as a direct result of rising carbon dioxide levels in the atmosphere—could spell trouble for the earliest stages of marine life, according to a new report.... " If other marine species respond similarly -- and there's no evidence yet that they don't -- then we're in trouble," said Jon Havenhand of the University of Gothenburg in Sweden. "The analogies are quite simple: we observed a 25 percent reduction in fertilization success at reduced pH, which is equivalent to a 25 percent reduction in the spawning stock of the species. Apply equivalent changes to other commercially or ecologically important species, such as lobsters, crabs, abalone, clams, mussels, or even fish, and the consequences would be far-reaching. It could be enough to 'tip' an ecosystem from one state to another."

That is, if we haven't fished the ocean to emptiness first.
