Earth Hour 2010 Online

Earth Hour, the WWF initiative started in Sydney in 2007, has been run for the fourth time, on a global basis. The 2.2 million Sydney homes and business who turned their lights off in 2007 have been joined across the world by millions of people making a stand against climate change. Well known landmarks the Sydney Harbour Bridge, the CN Tower in Toronto, the Golden Gate Bridge in San Francisco, and Rome’s Colosseum, were joined this year for the first time by Mount Rushmore in South Dakota, Niagara Falls at the U.S./Canada border, the Leaning Tower of Pisa in Italy, the Great Pyramids in Egypt, Table Mountain in South Africa, and the Hiroshima Peace Memorial in Japan.
