To produce 1 lb. of feedlot beef requires 7 lbs. of feed grain, which takes 7,000 lbs. of water to grow. Pass up one hamburger, and you’ll save as much water as you save by taking 40 showers with a low-flow nozzle. Yet in the U.S., 70% of all the wheat, corn and other grain produced goes to feeding herds of livestock. Around the world, as more water is diverted to raising pigs and chickens instead of producing crops for direct consumption, millions of wells are going dry. India, China, North Africa and the U.S. are all running freshwater deficits, pumping more from their aquifers than rain can replenish. As populations in water-scarce regions continue to expand, governments will inevitably act to cut these deficits by shifting water to grow food, not feed. The new policies will raise the price of meat to levels unaffordable for any but the rich. […]In the U.S., livestock now produce 130 times as much waste as people do. Just one hog farm in Utah, for example, produces more sewage than the city of Los Angeles. These megafarms are proliferating, and in populous areas their waste is tainting drinking water. In more pristine regions, from Indonesia to the Amazon, tropical rain forest is being burned down to make room for more and more cattle. Agriculture is the world’s biggest cause of deforestation, and increasing demand for meat is the biggest force in the expansion of agriculture.
