The one thing we all have in common around the world is our planet. Take an hour out of your day to join the rest of us and show your support for Earth. Turn your lights off for one hour at 8:30 pm local time. Half the world has already participated...min is in less than 4 hours. I just joined the website a few moments ago. Check out the page, there are some great shots of cities around the planet participating...literally the lights are off in the streets and skyscrapers. Global movements are difficult to organize, but grand when they can be pulled off. This all began in Australia in 2007... I remember Google's main page going black that year and reading up about it. We've participated in our small way every year since.
