Eating Expired Food is Normal in Antarctica | NOVA | PBS

Antarctic researchers burn through 3,200 to 5,000 calories a day just staying warm, on a continent where nothing grows and every meal has to be shipped in. This short follows hosts Caitlin Saks and Arlo Pérez through McMurdo Station's kitchen to see how hundreds of people get fed at the bottom of the world.
