Earth Hour: Switch off your lights for earth

To raise awareness, in 2007, our Leo Burnett colleagues in Sydney came up with Earth Hour, getting local government, the press and the residents and businesses of Sydney to switch off the lights for 1 hour. Because great ideas are worth repeating, 2009 will hopefully see another earth hour. By now, the concept has been exported to a whole bunch of other cities, and we hope that it catches on in Europe too.
