A global initiative created by the World Wildlife Fund, Earth Hour encourages individuals and businesses to turn off their lights for one hour to make a statement about conservation and climate change. This year's Earth Hour will take place this Saturday, March 28, starting at 8:30 p.m. The event started in Sydney, Australia in 2007, and it became a global event in 2008, with participants in 35 different countries and over 400 cities. This year it has grown even more with the WWF hoping to reach 1 billion participants worldwide. Already 2,500 cities in 82 countries have committed to participate.
