The LMEs produce about 80 of the annual world s marine fisheries catch. Globally they are centers of coastal ocean pollution and nutrient overenrichment habitat degradation e.g. sea grasses corals mangroves overfishing biodiversity loss and climate change effects. Large Marine Ecosystems LMEs are relatively large areas of ocean space of approximately 200 000 km or greater adjacent to the continents in coastal waters where primary productivity is generally higher than in open ocean areas.
