Researchers from Bard College in New York have found that the production of red meat releases more carbon into the atmosphere than any other meat product, and abstaining from it produces the most environmentally beneficial results. Cows require 28 times more land to raise than pigs or chickens, 11 times more water, and release 5 times the amount of greenhouse gases. The study shows that when it comes to reducing carbon footprints eating significantly less meat is more effective that abandoning your car.
