Earth Hour is an annual international event created by the WWF (World Wide Fund for Nature/World Wildlife Fund), held on the last Saturday of March, that asks households and businesses to turn off their non-essential lights and electrical appliances for one hour to raise awareness towards the need to take action on climate change. It was pioneered by WWF Australia and the Sydney Morning Herald in 2007 and achieved worldwide participation in 2008. Earth Hour will next take place on Saturday, March 28, 2009 at 8:30 pm, local time. Currently, 80 countries and 750 cities are 'committed to Earth Hour 2009', a huge increase from people participating in 35 countries for Earth Hour 2008. 1 billion 'votes' is the stated aim for Earth Hour 2009. Earth Hour 2008 was a major success, celebrated on all seven continents. Iconic landmarks all around the world turned off their non-essential lighting for Earth Hour which included the Empire State Building (New York City), Sears Tower (Chicago), Golden Gate Bridge (San Francisco), Bank of America Plaza (Atlanta), Sydney Opera House (Sydney, Australia), Wat Arun Buddhist Temple (Bangkok, Thailand), the Colosseum (Rome, Italy), Royal Castle (Stockholm, Sweden), London's City Hall (England), Space Needle (Seattle), and the CN Tower (Toronto, Canada). Google's homepage went "dark" on the day Earth Hour took place. According to a Zogby International online survey 36 million people participated in Earth Hour 2008, with an estimated 50 million doing the same around the world. The survey also showed there was a 4 percentage point increase in awareness of environmental issues such as climate change, directly after the event.
