The facts of the world water crisis are staggering. More than half of the global population today live in areas where there is no readily-available access to clean water. More than two billion people live without safe drinking water at home, and, incomprehensibly, nearly a billion people on this planet live without guaranteed access to water at all.
The effects of climate change will only worsen the horrifying situation. According to a Food Security report issued by the Natural Resources Defense Council, by 2025, nearly two-thirds of the world’s population will lack sufficient drinking water.
Human water use can only be substantively transformed by an equally substantive transformation in the human diet. Today, commercial agriculture accounts for 70 percent of water use worldwide. The majority of that water goes to growing commercial grain, and the majority of that commercial grain is used to feed the animals we eat.
The animals the average carnivore consumes each year have themselves consumed roughly one ton of grain during their lives. Since it takes roughly 1,000 tons of water to grow each ton of commercial grain, the average carnivore is consuming roughly 1,000 tons of water each year just to maintain their meat-based diet.
