Turn your lights off on March 27th, 2010 at 8:30 PM to show that you care about the environment. Earth Hour was created in 2007 by WWF in Australia. It did not took long for the idea to spread and to become a worldwide event.
A fun way to participate is to ask friends that live close by (so they can come by foot) to join you for a dinner made with local ingredients. Remind your friends to close their lights before they go out. Naturally, you will host a candlelight dinner. You could build a menu that does not require a lot of cooking time. For example, you could serve a local sustainable fish with a salad instead of cooked vegetables.
If you like to tweet about it, the hashtag is #EarthHour.
