Earth Hour
At 8pm on the 29 March 2008 millions of people in some of the world’s major cities used the simple action of turning off the lights for one hour to deliver a powerful message about the need for action on global warming.
Where did the lights go off?
Major participation took place in more then 25 major cities, on 6 continents, including Chicago, Copenhagen, Manila, Tel Aviv, Bangkok, Dublin and Toronto.
In total more than 400 more cities signed up to support this event in 2008.
Lights off at The Sydney Opera House, San Francisco's Golden Gate Bridge and Toronto's CN Tower meant world-famous city skylines disappeared for an hour while celebrities like Nelly Furtado hosted acoustic concerts for fans.
