On Saturday March 27th, 2010, millions of people from around the world turned off their lights as part of the World Wildlife Fund’s global Earth Hour campaign.
In Canada, homes and businesses, along with national monuments such as the CN Tower in Toronto, the Lion’s Gate Bridge in Vancouver and the Niagara Falls plunged into darkness.
Andy Ridley of the World Wildlife Fund told the CBC that he hoped this year’s Earth Hour will lead to a stronger climate deal than what world leaders managed to create at the Copenhagen summit last year.
The WWF started Earth Hour in Australia in 2007. By 2008, the initiative had become a global campaign against climate change.
