In 2005, hatchery-grown oyster larvae in the Pacific Northwest began mysteriously dying by the millions. Then it happened again in 2006. And again in 2007 and 2008. Oceanographers and fisheries scientists raced to understand what was behind the catastrophe. Was it bacterial infections? Or something more sinister?

By 2008, after billions of shellfish larvae had died, they had their answer. The waters of the Pacific Ocean had turned corrosively acidic.

The changes were too subtle to be noticed by swimmers and boaters, but to oysters, they were lethal. Many oyster larvae never made it to adulthood. Those that did suffered from deformed shells or were undersized. A $110 million industry was on the brink of collapse.
