Earth Hour 2008

Tomorrow, March 29, at 8pm is this year's Earth Hour.  It was done last year in a few cities with limited participation.  This year, they have put a lot more effort into raising awareness and getting global participation on both an individual and corporate scale.  Participants are asked to turn out their lights between the 8 and 9pm.  The idea is to demonstrate that such a small act, can make a measurable change.
