The effort's helmed by The Sustainable Fish City campaign, which is made up of food and conservation groups. The goal? Not only to use only sustainable seafood during the Olympic and Paralympic games, but also to adopt the same standards citywide, applying them across governmental organizations, including the transportation, fire, and police forces. Outside organizations have quickly followed, among them five top London universities, the National Trust, and the D&D group of London restaurants.
Not everyone thinks there's scientific basis for sustainable seafood guidelines, but in my opinion, this is a brave step forward. Could you see a US city following suit?
