Switch your lights off on Saturday evening

March 28th is not only my birthday: this year it's the Day of "Earth Hour", too. Everybody is called to switch their lights off for an hour at 20:30 h, and with the people of this world call for action against global warming.
2,848 cities, towns and municipalities in 84 countries have already committed to "Vote Earth". None in Germany, sigh. But still, we can participate, even if our government doesn't. Join us!
