If every American cut their red meat and poultry intake by half—down from four to two pounds a week—it would free up 150 million tons of grain. This kind of decrease wouldn’t constitute much of a sacrifice: two pounds of meat per week per person is generous compared with the consumption within many developed countries—it is still well more than the average consumption in Ukraine, for example. And the grain not used to make unnecessary meat for America would increase the world’s food-grain supply by a respectable 15 percent.
