Wildest Places — Episode 4: Icy Islands

You are watching the episode Icy Islands The Antarctic continent contains 90% of all ice on the planet. Deep in the center, conditions are so extreme that few forms of life survive. Even on the coast, seals and penguins need to enter water to warm up, and flee when Antarctica is plunged into 24-hour darkness each winter. The sheer inhospitable nature of the continent means the icy islands that surround it play a vital role.
