One billion people depend on seafood as their primary protein source
"“According to the United Nations Food and Agriculture Organization… About 1 billion people largely in developing countries rely on fish as their primary animal protein source. In 2010, fish provided more than 2.9 billion people with almost 20% of their intake of animal protein, and 4.3 billion people with about 15 % of such protein.”“Fish as Food,” Marine Stewardship Council, accessed December 10, 2014, http://www.msc.org/healthy-oceans/the-oceans-today/fish-as-food
