Alaska's Last Oil National Geographic Explorer : Season 22 Episode 12

Nowhere is the battle to find oil more intense than in Alaska - source of nearly 15% of America's domestic production, and home to the nation's largest wildlife preserve, the Arctic National Wildlife Refuge, where companies are pushing to drill. National Geographic travels back millions of years to see how oil was created, and looks to the future to ask how far we'll go to find every last barrel and at what cost.
