Ok folks it's time to go dark for an hour. Earth Hour is almost upon us, well except for those for whom it has already past (thanks to all who turned off their lights). For those of you who don't know what I'm talking about-- I took this from the Earth Hour website:

Earth Hour started in 2007 in Sydney, Australia when 2.2 million homes and businesses turned their lights off for one hour to make their stand against climate change. Only a year later and Earth Hour had become a global sustainability movement with more than 50 million people across 35 countries participating. Global landmarks such as the, Sydney Harbour Bridge, The CN Tower in Toronto, The Golden Gate Bridge in San Francisco, and Rome’s Colosseum, all stood in darkness, as symbols of hope for a cause that grows more urgent by the hour.... In 2009 over 4000 cities in 88 countries officially switched off to pledge their support for the planet, making Earth Hour 2009 the world’s largest global climate change initiative.

So tonight, turn off your lights (and yes your TVs, computers and IPhones--they all emit light. Heck turn off as much power as you can). As the Earth Hour folks say "It’s Showtime! Show the world what can be done."

And do not tell me that you can't turn off your lights for an hour because you don't know what you would do in the dark for an hour. I have total confidence in you all-- you will think of something!
