Who wants to listen to Leonardo DiCaprio, Al Gore, etc. as they jet from continent to continent, play on mega yachts, own 10,000 square foot homes-- then the listeners are supposed to live like monks?
No, that won't work. When they get real, concerned voices speaking-- people who put skin in the game-- then the idea might get traction.
