Whole Foods Market, the nation's leading natural and organic supermarket chain, has announced effective Earth Day (April 22), the retailer will be the first national grocer to no longer offer its customers any seafood carrying a "red rating," which the Blue Ocean Institute and the Monterey Bay Aquarium use to identify species that are either being overfished or employ methods used in catch that put ecosystems and other marine life at risk.

Eight ocean conservation organizations have joined forces to launch a social media campaign titled "Be Happy," in order to promote the importance of choosing sustainable seafood.
