Earth Hour 2012
This Earth Hour 2012: 8.30pm, Saturday 31 March, celebrate your action for the planet with the people of world by switching off your lights for an hour, then go beyond the hour!
I learned of this a little late, while visiting the World of Scout Movement website this morning. Scouting is promoting this quite strongly around the world. There is a random Flash video that opens when you first visit the WOSM website right now – pretty neat!
