Earth Hour 2011

I find it awesome that at 8.30 PM on Saturday 26 March 2011, lights will be switched off around the globe for Earth Hour. The campaign is organized by World Wildlife Fund (WWF).
Just imagine all the lights as seen in this satellite image of Europe, Middle East and North Africa going out one by one until this part of the globe lies in the dark... Incredible!
I wish I could see it from space!
