Puzzle for April 19, 2010

National Geographic Magazine started a TV Show called Human Footprint last year.

The point of the show is that over a human lifetime, we individually use a lot of resources. For instance, on average we eat 3576 pizza slices, eat 12888 oranges, and drink 26112 glasses of milk.

How many gallons of milk is that? (a glass is 8 oz)
