A new U.N. report states that a major driver of animal-to-human diseases is increased demand for animal protein. Duh! As populations get richer, they eat more meat. Since 1961, global meat production has more than quadrupled. Americans are among the top meat consumers in the world. In 2018, each of us ate, on average, 222 pounds of red meat and chicken. Consumption in most other countries is far lower, but rising. In China, meat consumption has doubled since 1990.
