Cheeseburger footprint

It's estimated that the average, omnivorous American eats three cheeseburgers per week. Ignoring the caloric and fat intake, the environmental footprint adds up.

Check out this clip from National Geographic's "Six Degrees," featuring Jamais Cascio, who's done a significant amount of research in determining the footprint of the cheeseburger. Many of you may have seen it, but it's worth looking at again, and, maybe, cutting back or eliminating some ground beef from your diet.
