Alaska's Last Oil DVD
Alaska's Last OilDVD
The world is addicted to oil. But now the easy pockets of oil are gone and the race is on to find new sources. Nowhere is the battle more intense than in Alaska - source of nearly 15% of Americas domestic production, and home to the nations 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 well go to find every last barrel and at what cost.
