TEXT 1 Text 1 is a script taken from the beginning of Episode 1 of Frozen Planet. The episode is titled ‘To The Ends of The Earth’, and focusses on the wildlife that lives in the Polar Region.

Over one third of our planet is frozen, and yet the icy worlds of the Arctic and Antarctic are as alien to most of us as the surface of another planet. They are places of superlatives, from ice caps that hold nearly 80% of our planet's fresh water to frozen forests that encircle the entire globe. These are places that feed our imaginations, places that seem to be borrowed from fairy tales. They're dominated and shaped by the ice, both by its coming and by its going. This is our planet's last true wilderness and one that is changing just as we are beginning to understand it. In this series we'll be travelling to all parts of these lonely lands, both north and south, to witness its wonders, perhaps for the last time, and to discover some extraordinary examples of survival against all the odds as can be found anywhere on the planet. The Poles are permanently capped with ice. Nowhere is colder, windier or more hostile to life. I'm standing at the North Pole, the very top of the Earth. Up here, it's easy to see why the Polar Regions are so cold. The sun never rises high enough in the sky to warm my back and those rays that do strike the surface are mostly reflected back from this great whiteness. But the fundamental problem is that there's no sun here at all for half the year. The polar winter is unrivalled in its harshness, a night that lasts for months. Only the toughest stay, as temperatures plunge to minus 70 degrees centigrade. And yet the greatest challenge to life here is not the cold, but the extreme swings between the seasons. When the sun finally returns, an extraordinary transformation begins. This frozen world begins to melt away. The polar spring brings a brief opportunity for life. By summer, the sun no longer sets and works its magic for 24 hours a day.
