Meat-eating wastes resources More than half of all water used for purposes in U.S. is put into livestock production. The amount of water used for raising an average cow is enough to float a naval destroyer. A pound of wheat needs only 25 gallons of water, while a pound of beef needs 5000 gallons. It also takes 78 calories of fossil fuel to produce one calorie of beef protein while it only takes 2 calories to produce one calorie of soybean.
