According to the New Scientist, It's better to green your diet than your car. [via postcarbon.org]
"The typical US diet, about 28 per cent of which comes from animal sources, generates the equivalent of nearly 1.5 tonnes more carbon dioxide per person per year than a vegan diet with the same number of calories, say the [U of Chicago] researchers, who presented their results at a meeting of the American Geophysical Union in San Francisco last week.

"By comparison, the difference in annual emissions between driving a typical saloon car and a hybrid car, which runs off a rechargeable battery and gasoline, is just over 1 tonne. If you don't want to go vegan, choosing less-processed animal products and poultry instead of red meat can help reduce the greenhouse load."
