The Vegetarian Resource Group produced a brochure called “Save Our Water—The Vegetarian Way” looking at water usage and livestock production versus water usage and eating a veggie diet. One chart shows the estimated amount of water in liters used to produce one kilogram of food in the U.S. Another chart shows global averages of the quantity of water required to produce certain food products by liters. We also present the quantity of grains (kg) eaten by U.S. livestock to produce one kilogram of meat. Three sets of statistics are presented due to differing calculations by various statistics.
