Rising Meat Consumption Takes Big Bite out of Grain Harvest
Earth Policy Release
November 22, 2011
World consumption of animal protein is everywhere on the rise. Meat consumption increased from 44 million tons in 1950 to 284 million tons in 2009, more than doubling annual consumption per person to over 90 pounds. The rise in consumption of milk and eggs is equally dramatic. Wherever incomes rise, so does meat consumption.
As the oceanic fish catch and rangeland beef production have both leveled off, the world has shifted to grain-based production of animal protein to expand output. With some 35 percent of the world grain harvest (760 million tons) used to produce animal protein, meat consumption has a large impact on grain consumption, and therefore global food security.
The efficiency with which various animals convert grain into protein varies widely. Grain-fed beef is one of the least efficient forms of animal protein, taking roughly 7 pounds of grain to produce a 1-pound gain in live weight. Global beef production, most of which comes from rangelands, has grown by about 1 percent a year since 1990.
