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 percent 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.''
Ben & Jerry's ice cream might be even more sinister: A gallon of it requires electricity guzzling refrigeration, and four gallons of milk produced by cows that simultaneously produce eight gallons of manure and flatulence with eight gallons of methane. The cows do this while consuming lots of grain and hay, which are cultivated by using tractor fuel, chemical fertilizers, herbicides and insecticides, and transported by fuel-consuming trains and trucks.
Newsweek says most food travels at least 1,200 miles to get to Americans' plates, so buying local food will save fuel. Do not order halibut in Omaha.
Just stop eating meat and vegetables all together!
