Oyster extravaganza!

Valentine’s weekend may be your best chance to eat oysters for years to come

Ocean acidification is a worldwide phenomenon related to the accumulation of excess carbon dioxide in the atmosphere. The ocean absorbs the carbon dioxide, which makes the water more acidic. This increased acidity has myriad effects on ocean chemistry. Among other things, it retards the ability of marine microorganisms to turn calcium into shell. Ocean acidification has already been blamed for a slowdown in the creation of coral reefs. It may also be the reason that oyster larvae in West Coast hatcheries are dying before they form shells.
