Thanksgiving dinner's carbon footprint

As if you need another reason to feel guilty about chowing down on Thanksgiving Day, consider this: researchers at the University of Manchester in England figure that a turkey-n-trimmings feast for eight produces approximately 44 pounds of carbon dioxide emissions. About 60% of that planet-warming gas comes from the life cycle of the turkey, alone. And that doesn't include drinks.
