Meeting Global Protein Demand: Weighing the Impacts of Land and Sea Food Production

Drawing from several global syntheses, Elliott will set the stage for the symposium by examining the current global picture of food demand and supply and its projected change over the rest of this century. About 20% of the protein that humans consume comes from the sea, and roughly a billion people, largely in the developing world, obtain the majority of their protein from fish. Does meeting global demand from marine sources pose fewer environmental impacts than expanding production on land?
