At 8pm on Saturday, March 29th, 2008 the lights are going out in hundreds of thousands of homes and businesses around the world. From South Africa to Scotland, from Canada to Vietnam, a globally choreographed event will make a statement. A statement about the importance and feasibility of global environmental action. This is the second annual Earth Hour.

Earth Hour started in 2007 in Sydney, Australia. After seeing the environmental impact of light pollution and wasted energy, Earth Hour has gone global under the sponsorship of the non-profit environmental protection and conservation organization WWF  (http://www.wwf.org/).

The light sensitive satellite image of Europe shows areas of high and low light pollution. Light pollution is directly tied to a number of environmental hazards, including CO2 production.  The red and orange areas represent the highest levels of light pollution and the blue and black areas represent areas of lowest light pollution. To find out how countries have gone blue by being green, WWF has created a guide to sustainable living that wont cramp your lifestyle, available for purchase at http://www.wwf.org/shop/categories/sustainableliving. To see how bright your region lights up, check out the Live Maping Table at http://www.earthhour.org/about/ranking.
