Rapid predicted worldwide growth in demand for animal products to 2020, the so-called “next food revolution” in animal agriculture, portends complex interactions among people, biological and geophysical resources, and economic objectives. Consumer demand for beef and pork is expected to increase by 2.8% per year, somewhat slower than demand growth for poultry meat (3.1%/yr). Demand for dairy products is predicted to grow fastest, at 3.3%/yr (Delgado et al., 1999).
