Saturday, March 28: Participate in Earth Hour!

Did you participate in Earth Hour last year? I did, and the vibes felt great. And now we'll have another opportunity this Saturday.

On March 28 at 8:30 pm local time, individuals, businesses, and municipalities around the world will turn off their lights for one hour -- Earth Hour -- in a show of concern for climate change and commitment to finding solutions.

In 2008, some 50 million people participated in 35 countries.

This year, according to the Earth Hour website, "hundreds of icons and landmarks around the world have signed up to turn their lights off for Earth Hour 2009 including - the Eiffel Tower in Paris, Sydney Opera House, Acropolis and Parthenon in Athens and The London Eye, among many others."

And I just learned that Washington, DC, will turn off all non-essential lighting on city-owned buildings and facilities during Earth Hour.

To find out more, and to sign up, go to www.earthhour.org.

If enough people, businesses, and cities participate, imagine how dramatic it would look from space as darkness rolls through the earth's time zones one by one!
