“Farmers and ranchers make up just 1 percent of the U.S. population but manage two-thirds of the nation's land; agriculture has greater impacts on water, land and terrestrial biodiversity than any other human enterprise....Half of Earth's ice-free land is in pasture or farms. Crops now cover an area the size of South America and livestock graze an expanse as big as Africa; together they use 70 percent of all fresh water. Fishermen have an equally enormous impact, harvesting 90 million metric tons of fish annually-equivalent, as author Paul Greenberg calculates, to pulling the human weight of China out of the sea every year.” FishingSustainabilityAgricultureConservationFarmingLand UseEnvironmental ImpactRanching Book:Rancher, Farmer, Fisherman: Conservation Heroes of the American Heartland Source: Rancher, Farmer, Fisherman: Conservation Heroes of the American Heartland
