Polar zones

Narrated by Sir David Attenborough and from the award-winning team behind Planet Earth & Blue Planet comes the ultimate portrait of the earth's Polar regions. The Arctic and Antarctic remain the greatest wildernesses on Earth. The scale and beauty of the scenery and the sheer power of the elements - the weather, the ocean and the ice - is unmatched anywhere else on our planet.

For many years, concerns have been expressed about environmental issues in the Arctic. While the Arctic region, unlike Antarctica, has been inhabited for thousands of years, it is under unique threat because of its vulnerability toward resource exploitation and the deposition of various airborne pollutants. With its varied populations, and with eight Nations asserting territorial interests, the Arctic needs a careful approach to its protection and development.
