Giving up meat could drastically reduce your carbon footprint, with meat-eaters' diets responsible for almost twice the emissions of those of vegetarians.

A diet with meat is responsible for producing in a year the same amount of greenhouse gases as driving a mid-sized car -- 2,956 miles.

I posted about this back in January:

If Americans were to reduce meat consumption by just 20 percent it would be as if we all switched from a standard sedan -- a Camry, say -- to the ultra-efficient Prius.

Of course:

In all his speeches, John McCain urges Americans to make sacrifices for a country that is both “an idea and a cause”.

He is not asking them to suffer anything he would not suffer himself.

But many voters would rather not suffer at all.
