People need to know about 350.  So, when YouTube invited video submissions to its 2009 Davos Debates, I saw it as an opportunity that should not be missed.   World leaders will be meeting at the World Economic Forum (starting January 28, 2009) in Davos Switzerland..an ideal forum for  raising  the profile of 350.  After checking out this 8-minute video, there should be no question why Bill McKibben calls 350 the most important number on the planet.  And do watch it right to the end – past the credits.  For me, it’s the best part.
