Earth Hour started in 2007 in Sydney, Australia when 2.2 million homes and businesses turned their lights off for one hour to make their stand against climate change. In March 2009, hundreds of millions of people in over 4000 cities in 88 countries switched off their lights to pledge their support for the planet, making Earth Hour 2009 the world’s largest global climate change initiative.
