Major cities went dark on Saturday, 28 March 2009 for Earth Hour, becoming part of the global protest against climate change. From an Antarctic research base to the Great Pyramids of Egypt and beyond, the world switched off the lights on Saturday for Earth Hour, dimming skyscrapers, city streets and some of the world's most recognizable monuments for 60 minutes to highlight the threat of climate change.























The initiative, Earth Hour, was begun in Sydney two years ago by green campaigners keen to cut energy use. Millions of people world-wide cast their votes in support of the Earth, urging world leaders to take action to fight global warming. The results will be presented at the 2009 Global Climate Change Conference in Copenhagen.
Celebrate and visit Earth Hour.
