IF YOU TAKE YOUR CAR to go to a McDonalds drive-in restaurant, where do you think the real harm to the environment is?

2.2lb of beef is responsible for greenhouse gas emissions which have the same effect as the carbon dioxide released by an ordinary car travelling at 50 miles per hour for 155 miles, a journey lasting three hours. The amount of energy consumed would light a 100-watt bulb for 20 days.

Most of the greenhouse gas emissions are in the form of methane released from the animals' digestive systems, New Scientist magazine reported.
