S1, E5: Bruce heads to a remote Russian village, deep within the vast boreal forest that stretches for thousands of miles across the top of the world. Life here has changed little for hundreds of years, and people still depend on the food they gather from the woods. Bruce then travels north into Norway where he lives with the Saami, reindeer herders who use snow machines, boats and even helicopters to move their animals. His last stop is a remote scientific community in the Svalbard archipelago where he learns about the fragility of Arctic ecosystem.
