 Marine fisheries comparing countries' current percent dependence on marine foods for nutrition compared with projected change in maximum catch potential  from marine fisheries. The percentage of animal sources foods consumed that originate from a marine environment. Countries with higher dependence are indicated by darker shades . Projected percent change in MCP of marine fisheries under 1.6°℃ global warming and >4℃ global warming from recent past  to end of 21st century  in countries' Exclusive Economic Zones  . Darker shades indicate greater percent reduction . Countries  that have overlap between high nutritional dependence and high reduction in MCP under two warming scenarios.
