March 27, 2010 will bring with it the fourth annual Earth Hour -- the world's largest switch-off. Organized by the World Wildlife Fund, Earth Hour is designed as a non-partisan movement, where the world's communities, governments and organizations can come together to do something about climate change. To quote WWF:
'The movement symbolizes that by working together, each of us can make a positive impact in this fight, protecting our future and that of future generations.'
If you want to participate, it's easy: simply turn off your lights for one hour on March 27, 2010 at 8:30pm local time.
Last year nearly 1 billion people world-wide took part, including those in 4100 cities in 87 different countries. International landmarks to participate include France's Eiffel Tower, the Empire State Building, Beijing's Forbidden City, London's Parilment, the Las Vegas Strip, Christ the Redeemer Statue in Rio de Janeiro, St. Peter’s Basilica in Vatican City and more.
The "switch-off" will begin on an island in the South Pacific, and finish in the Galapagos Islands, almost 25 hours later on the other side of the international dateline. Scientists at the Charles Darwin Research Station have planned a candle-lit dinner with locals and environmentalists.
