OK, I'm not buying a literal 2000 pound ton -- if I did that I'd eat 'em all in one sitting. But get 'em while you can; they might not be around much longer.
Vancouver Sun:
>> Ten million scallops that have died in the waters near Qualicum Beach due to rising ocean acidity are the latest victims in a series of marine die-offs that have plagued the West Coast for a decade.
Human-caused carbon dioxide emissions in the atmosphere are being absorbed by the ocean and may have pushed local waters through a “tipping point” of acidity beyond which shellfish cannot survive, according to Chris Harley, a marine ecologist at the University of B.C. Rising ocean acidity is a global phenomenon, made worse by higher natural acidity in local waters, Harley said.
“I’ve seen pH measured down to about 7.2, so this is very much within the realm of possibility, though unfortunate and extreme,” he said. “We are in a hot spot in the Pacific Northwest.” The lower the pH, the higher the acidity. Local waters are typically a much-less-acidic 8.2.
High acidity interferes with the ability of baby scallops to form a protective shell, forcing them to expend more energy and making them more vulnerable to predators and infection.
... “In 2009 we started to notice significant problems in the hatchery and when we communicated with hatcheries in Washington, they were seeing the same thing,” he said. “Suddenly we were getting these low pH values. pH has been so stable that for a lot of years no one bothered to measure it, because it never changed. It was really startling.”
Scallop operations big and small are reporting die-offs this year. Mysterious scallop die-offs have also been reported in China since 1996.
Oyster die-offs in Washington state and Oregon dating back a decade have also been linked by National Oceanic and Atmospheric Administration researchers to acidification and rising carbon dioxide levels.
... Carbon dioxide concentrations that had been stable for as long as records were kept started to climb and, rather than correcting, they stayed high. By 2011, concentrations were verging on double the normal range, he said. <<
(some emphasis added)
But you know what --- naaah, let's just continue to pretend dumping an unnatural balance of CO2 into the biosphere has no consequences. Addressing a bad practice is just so hard, let's take the path of least resistance, have an ice-cold Koch and get on with business as usual.
