Ideas: In Praise of Ice, part 1

Saturday,  January 23, 2010 9pmPart 1: Ice and the Evolution of Life on Planet EarthProducer: CBC Radio OneListen AgainFor more than four billion years, ever since comets first crashed into the Earth, ice has been inextricably linked to life on this planet. From cold-hardy microbes to freeze-resistant frogs, nature has evolved many tricks for survival. Even human beings have learned to adapt to the challenges – and opportunities – of life with ice. Now, as glaciers shrink and ice vanishes from the polar seas, Richard Longley takes us back to our icy roots, rekindling wonder for this alluring frozen water.
