The polar caps have the most extreme seasonal contrasts, growing and melting vast ice masses, so wildlife adapts by annual migrations. The majority of Antartica is a vast barren permafrost. Only 3% of the coast and peninsular peaks are where life migrates to in the spring, for a short fertile summer, attracted by rich supplies of krill and fish. Only the Emperor penguin males breed 4 months in winter 100 miles inland. The Arctic has a more complete fauna which migrates back North from the continent. Here, the Polar bear is threatened because global warming defrosts its seal hunt platform ice too fast. Written by KGF Vissers

[first lines]
David Attenborough - Narrator: Both poles of our planet are covered with ice. They're the largest and most demanding wildernesses of all. Nowhere else on Earth is seasonal change so extreme. It causes the ice to advance and retreat every year. And all life here is governed by that.

Mind boggling - stunning visuals
5 February 2007 | by ageagainstthemachineSee all my reviews

If you have ever pondered that there are wonderful, beautifully natural things in far away places, you will surely be proved correct by this stunning doco. From the appearance of it, shooting this amazing collection of stories of many animals in the Arctic circle and Antarticta would have taken months upon months. Attenborough's regard of the natural world and his pacing is solid as always, yet the unique aspect of this production is the images included. UNIQUE shots. Being a camera operator in the freezing cold landscape would have been my dream on such a production. Polar bears swimming across an ocean, filmed from 30 feet above, time lapse sequences that track the midnight sun as it skirts across the horizon for 24 hours, time lapse of a large group of penguins being battered by gales as they huddle together for warmth. The many camera operators of this are truly dedicated to their passion. As the credits rolled, I couldn't help but ask myself and everyone in the room - 'how the hell did they get those shots'. If a fan of stunning cinematography amongst the natural landscape, do yourself a favour and get the Planet Earth DVD.
