Earth hour 2011 (EH 60+)

Within the global Earth Hour project, organized by WWF, cities around the world will turn off the lights starting at 20.30, on 26 March 2011, in order to send a powerful message that it is possible to take concrete measures against global warming. Turning the lights off for an hour is not enough. We urge you to make a decision on what else you can do to contribute to saving our planet.
