How many canaries in the coal mine comparisons are there now on planet earth in terms of specific species crashing and ecosystems degrading?

Even one of the businessmen as part of the Whiskey Creek Shellfish Hatchery said the hatchery's chemistry manipulations were just "scratching the surface" in terms of how big and far-reaching ocean acidification will be. The shellfish hatchery game, over in 20 or 30 years?

"It was here, from 2006 to 2008, that oyster larvae began dying dramatically, with hatchery owners Mark Wiegardt and his wife, Sue Cudd, experiencing larvae losses of 70 to 80 percent.

'Historically we've had larvae mortalities,' says Wiegardt, but those deaths were usually related to bacteria. After spending thousands of dollars to disinfect and filter out pathogens, the hatchery's oyster larvae were still dying.

Finally, the couple enlisted the help of Burke Hales, a biogeochemist and ocean ecologist at Oregon State University. He soon homed in on the carbon chemistry of the water. 'My wife sent a few samples in and Hales said someone had screwed up the samples because the [dissolved CO2 gas] level was so ridiculously high,' says Wiegardt, a fourth-generation oyster farmer. But the measurements were accurate. What the Whiskey Creek hatchery was experiencing was acidic seawater, caused by the ocean absorbing excessive amounts of CO2 from the air."

Now is the time (30 years ago, really) to get communities to talk, to come up with collective solutions, to challenge business as usual, and science as usual.

And a flat-lined media, or so-called liberal press will not be benefiting anyone in terms of getting community conversations going and action started. If a rag or TV network is around just to sell junk, then, we have no hope.

One restaurant and seafood market owner I talked with in Newport is aware that her five-star restaurant and local sourcing of seafood is small time in the scheme of things. Her story, again, will be in the Newport News Times.

"There are so many forces beyond our control. I am worried about long-term food security. I want us to be looking at food systems, and to teach that in academic settings," said Laura Anderson of Local Ocean Dockside Grill and Fish Market.
