In 2013 the U.S. produced about 13 million tons, almost more than in 1976. Laughtered 10 million fewer cattle, from a herd that was almost 40 million head smaller. The average slaughter animal packs 23 percent more meat these days than in 1976. |
The portion of the U.S. grain harvest consumed by all animals, 81 percent then, has plummeted to 42 percent today, as yields have soared and more grain has been converted to ethanol. Ethanol now consumes 36 percent of the available grain, beef cattle only about 10 percent. Still, you might think that if Americans ate less beef, more grain would become available for hungry people in poor countries. |
