The steady growth of global meat production comes at considerable cost. Industrial methods in the livestock sector cut down forests to expand grazing lands and use large quantities of water. Production uses grains (such as corn or soybeans) for animal feed and relies on heavy doses of antibiotics in animals. Beef is particularly resource-intensive. Limiting these environmental and health impacts requires not only a look at how much meat people eat, but also at the kind of meat that they consume worldwide.
