The Blue Food Revolution

Meat consumption is rising worldwide, but production involves vast amounts of energy, water and emissions. At the same time, wild fisheries are declining. Aquaculture could become the most sustainable source of protein for humans.Fish farming already accounts for half of global seafood production. Most of it is done along coastlines, which creates substantial water pollution.

Large, offshore pens that are anchored to the sea floor are often cleaner. Those farms, other new forms of aquaculture, and practices that clean up coastal operations could expand aquaculture significantly. Questions remain about how sustainable and cost-effective the approaches can be.
