Raising livestock has apparently contributed to water scarcity. Tracing back to farming processes that require the use of water, like growing food for livestock, meat production is clearly a water intensive process. “Eat a steak or a chicken and you are effectively consuming the water that the animal has needed to live and grow,” author of McLibel: Burger Culture on Trial, John Vidal, said. Additionally, vegetarian author, John Robbins, once calculated and compared the pounds of water needed to produce a pound of vegetables like potatoes (60 lbs.), wheat (108 lbs.), maize (168 lbs.), and rice (229 lbs.) as opposed to a pound of beef (9,000 to more than 20,000 lbs.).
