In fin d'annÃ©e mood, saving the world is en vogue -- and asking the "one thing" question obviously, too.
Inspired by Leonardo DiCaprio's gloom and doom documentary "The 11th Hour," OnEarth magazine asked a panel of leading scientists and activists to "move beyond bleak diagnoses and offer concrete proposals for a sustainable future:"
"Which one thing would you do to save the world?"
In a similar vein, but slightly modifying OnEarth's impetus (and oddly phrasing it), The World Economic Forum (WEF) asks the "Davos Question:"
"What one thing do you think that countries, companies or individuals must do to make the world a better place in 2008?"
Unlike OnEarth, however, the WEF does not seek the advice of experts and instead relies on the crowd. Everyone can upload suggestions on YouTube and make his/her "voice heard in Davos." The highest rated videos will be screened on January 23-27 during the Forum. The world leaders will then be asked to video-respond on YouTube.
