Polar bears feast on the remains of bowhead whales on the edge of the Beaufort Sea while cultural anthropologist Richard Nelson describes their actions, explains their lives, humans' historical relationship to Polar bears, and their chances for survival. This is a rerun of a 2008 Sprouts edition by a show, no longer in production, called "Encounters," that brought the sounds of the northern wild to the radio. Produced for Sprouts by Lisa Busch and Richard Nelson at KCAW in Sitka, Alaska.
