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.
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.
