Globally, about 17% of humans' average per capita intake of animal protein in 2017 came from marine and freshwater wild-caught and aquacultured aquatic animals . Per capita intake of seafood is 50% or more in some Small Island Developing States  , and consumption per capita is 15 times higher in Indigenous Peoples than non-Indigenous Peoples . Fishery products also supply critical dietary micronutrients worldwide . Marine and freshwater fisheries and aquaculture provide livelihoods for an estimated 10-12% of the world's population . Fishing and aquaculture provide women and their families with substantial amounts of food and income , because at least 11% of small- scale fishers  and up to half of all fishery and aquaculture workers  are women. This section assesses how climate-driven alterations of the abundance or nutritional quality of food from the sea could affect humans. Aquaculture, catch potential changes and human adaptations to changes in wild and cultured harvests are assessed in Section 5.9.
