Meat
Appetite for meat is growing as the developing world becomes more prosperous. But meat – especially beef – can be polarizing, on health, environmental and ethical grounds. Chicken outpaced beef in the United States in 2010. Per capita beef consumption in the U.S. peaked in 1976 at 91.5 pounds a year; it has since fallen more than 40 percent. Argentina’s famous appetite for beef has fallen because of cholesterol consciousness and economic downturns. In countries where meat is a newly affordable option, animal protein is a boon, not a debate.
