Still Cool to All the Warming Warnings - WSJ.com

Nature designed us as carnivores, but what does nature know about nature? Meat has been designated a menace. Among the 51 exhortations in Time magazine's "global warming survival guide" (April 9), No. 22 says a BMW is less responsible than a Big Mac for "climate change," that conveniently imprecise name for our peril. This is because the world meat industry produces 18% of the world's greenhouse-gas emissions, more than transportation produces. Nitrous oxide in manure (warming effect: 296 times greater than that of carbon) and methane from animal flatulence (23 times greater) mean that "a 16-ounce T-bone is like a Hummer on a plate."
