Earth Hour 2009

Started in Sydney, Australia in 2007, Earth Hour quickly grew into a global observance. More than 1,000 cities in over 80 countries observed Earth Hour 2009 on Saturday March 28th, as homes, office towers and landmarks turned off their lights for an hour starting at 8.30 pm local time to raise awareness about climate change and the threat from rising greenhouse gas emissions. Collected here are a series of before-and-after photographs - which (starting with the second one below) will fade between "on" and "off" when clicked. Let me state that again, since I know not everyone reads the whole intro here - starting with image #2 below, click on the image to see an animated fade between "on" and "off".
