When it comes to global warming, hamburgers are the Hummers of food, scientists say.
Simply switching from steak to salad could cut as much carbon as leaving the car at home a couple days a week.
That's because beef is such an incredibly inefficient food to produce and cows release so much harmful methane into the atmosphere, said Nathan Pelletier of Dalhousie University in Canada.
Pelletier is one of a growing number of scientists studying the environmental costs of food from field to plate.
By looking at everything from how much grain a cow eats before it is ready for slaughter to the emissions released by manure, they are getting a clearer idea of the true costs of food.
The livestock sector is estimated to account for 18 percent of global greenhouse gas emissions and beef is the biggest culprit.
Even though beef only accounts for 30 percent of meat consumption in the developed world it's responsible for 78 percent of the emissions, Pelletier said Sunday at a meeting of the American Association for the Advancement of Science.
That's because a single kilogram of beef produces 16 kilograms carbon dioxide equivalent emissions: four times higher than pork and more than ten times as much as a kilogram of poultry, Pelletier said.
If people were to simply switch from beef to chicken, emissions would be cut by 70 percent, Pelletier said. More here:

Little by little they take your freedom. Little by little they get you to abandon the ideas of capitalism and move you to communism. All by making you feel guilty about one thing or another. YOU MUST SAVE THE PLANET - FORGET YOUR FREEDOM. They attack everything you do so you don't notice the things that really matter.
Do they have you fooled? Are you buying all the "science" they're citing? I'm talking to YOU. Perhaps I should use your native language. "Mooooo," oops, I mean "Bleat Bleat." Get it? Vote for liberals!!
