Earth Hour is a worldwide event organized by the World Wide Fund for Nature (WWF) and held towards the end of March annually, encouraging households and businesses to turn off their non-essential lights for one hour to raise awareness about the need to take action on climate change.
In 2013, the Earth Hour 2013 will be held on March 23, 2013 from 8:30 p.m. to 9:30 p.m. during participants’ local time.
The participation in the Earth Hour has increased by leaps and bounds over the years. From 2.2 million participants in 2007 to an event that reached an estimated 1.8 billion people in 2012, the organization has come a long way.
On this day, at that time Sydney Opera House, Great Wall of China, the Burj Khalifa, the Eiffel Tower, Christ the Redeemer, the Empire State Building, Cape Town’s Table Mountain, the Statue of David in Florence, Tokyo Tower, Taipei 101, the Bird’s Nest in Shanghai, Kuala Lumpur’s Petronas Towers, the Gateway of India in Mumbai, the walls of Dubrovnik, Buckingham Palace in London, Times Square in New York, Niagara Falls, Toronto’s CN Tower and the Las Vegas Strip, and countless others will go dark.
We here aturge all those who read this message to turn all nonessential lights off for one hour Saturday between 8:30 and 9:30 p.m. local time on 23rd March 2013.
