Eating Beef is Less Green than Driving

Invisible Pink Unicorn writes: "Japanese scientists have calculated the overall effect on the environment of producing beef for consumption, and show that 2.2lb of beef generates as much greenhouse gas as driving a car non-stop for three hours at 50mph. The amount of energy consumed would light a 100-watt bulb for 20 days. Taking into account all the processes involved, they said, four average sized steaks generated greenhouse gases with a warming potential equivalent to 80.25lb of carbon dioxide. Most of these emissions are in the form of methane released from the animals, but over two thirds of the energy is used to produce and transport cattle feed."
