（单词翻译）

 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 are dominated and shaped by the ice, both by its coming and by its going. This is our planet's last true wilderness1, and one that is changing just as we're beginning to understand it.
 
In this series, we'll be traveling 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 odds2 as can be found anywhere on the planet.
 
The poles are permanently3 capped with ice. Nowhere is colder, windier or more hostile to life.
