Approximately 60% of humanity live in areas of water stress, in other words living without water close to home. Nearly a billion of those people live without any access to water whatsoever, a number just a bit higher than the populations of the U.S., Indonesia, and Brazil.
According to a Food Security report issued by the Natural Resources Defense Council, global climate change will stress water resources and lessen both crop and livestock productivity.By 2025, nearly two-thirds of the world’s population will lack sufficient drinking water.
It is now common knowledge that a meat-based diet has a disproportionate effect on global water resources. Waste from factory farmed animals poison rivers, aquifers, and estuaries. Expanding grazing lands cause massive deforestation. The majority of the water we now use as a species goes to growing commercial grain. Since the animals the average western carnivore consumes each year will have themselves consumed roughly one ton of grain (which takes roughly 1,000 tons of water to grow), those carnivores are actually consuming about 1,000 tons of water annually just to maintain the meat in their diet.
