According to a 2006 United Nations report, livestock accounts for 18 percent of worldwide greenhouse gas emissions. Some of meat’s contribution to climate change is intuitive. It’s more energy efficient to grow grain and feed it to people than it is to grow grain and turn it into feed that we give to calves until they become adults that we then slaughter to feed to people. Some of the contribution is gross. “Manure lagoons,” for instance, is the oddly evocative name for the acres of animal excrement that sit in the sun steaming nitrous oxide into the atmosphere. And some of it would make Bart Simpson chuckle. Cow gas — interestingly, it’s mainly burps, not farts — is a real player.
But the result isn’t funny at all: Two researchers at the University of Chicago estimated that switching to a vegan diet would have a bigger impact than trading in your gas guzzler for a Prius (PDF). A study out of Carnegie Mellon University found that the average American would do less for the planet by switching to a totally local diet than by going vegetarian one day a week. That prompted Rajendra Pachauri, the head of the United Nations Intergovernmental Panel on Climate Change, to recommend that people give up meat one day a week to take pressure off the atmosphere. The response was quick and vicious. “How convenient for him,” was the inexplicable reply from a columnist at the Pittsburgh Tribune Review. “He’s a vegetarian.”
