Created to take a stand against the great threat our planet is now facing, Earth Hour uses the simple action of turning off the lights for one hour to deliver a powerful message about the need for action on global warming.
Earth Hour first started in Sydney, Australia. On 31 March 2007, 2.2 million people and 2100 Sydney businesses turned off their lights for one hour, producing the world's first Earth Hour. If the greenhouse reduction achieved during that one hour in Sydney was sustained for a year, it would be equivalent to taking 48,616 cars off the road for a year.
This simple act has captured the hearts and minds of people all over the world. As a result, at 8pm March 29, 2008 millions of people in some of the world's major capital cities will unite and turn their lights off for one hour to join together in a global Earth Hour.
