Earth Hour started last year, March 31, in Sydney, Australia, when 2.2 million people and 2,100 businesses turned off their lights for one hour in hopes of inspiring the rest of the world to take action on climate change. Sydney icons such as the Harbour Bridge and Opera House turned off their lights, weddings and other events were held in candlelight, and the world took notice.
What was the environmental impact? If the greenhouse reduction achieved in Sydney during Earth Hour 2007 was sustained for a year, it would be equivalent to taking 48,616 cars off the road for a year.
As of today's date, nearly 200,000 individuals and over 13,000 companies have officially signed up on the Earth Hour Web site. Cities around the world have also pledged their participation, too. According to the Earth Hour Site, “Chicago will serve as the U.S. flagship city for Earth Hour in 2008, with Atlanta, Phoenix and San Francisco joining as leading partner cities. But everyone throughout the US and around the world is invited and encouraged to turn off their lights . . . whether at home or at work, with friends and family or solo, in a big city or a small town.”
So, let’s spread the word. Then turn off those lights!
