This document summarizes the environmental impact of meat production and how vegetarians and vegans are helping the planet. It notes that producing one pound of meat requires 7 pounds of grain and 2400 gallons of water, compared to only 14 gallons needed for one pound of wheat. By going vegetarian or vegan, an average American could save 596,500 gallons of water, 1,500 pounds of grain, and reduce their carbon footprint by over 200 pounds per year by eliminating the 250 pounds of meat they typically consume annually. Going meatless just one day a week can provide significant environmental benefits as well.
