C'mon its just 1 hour !

Rome's Colosseum is one of many famous buildings around the world where floodlights will be turned off during Earth Hour.

Between 20:30 and 21:30 on the evening of Saturday 28 March the organisers of the Earth Hour 2009 campaign aim to get as many people as possible to turn off their lights as a mark of concern about climate change.

More than 1,000 cities and countless firms, organisations and citizens in more than 80 countries around the world have already promised to turn off their lights between 20:30 and 21:30 local time next Saturday evening. The worldwide Earth Hour 2009 campaign is being co-ordinated by WWF. The campaign has become a truly global phenomenon since its launch in Sydney, Australia in 2007.

“The latest findings show that climate change is progressing even faster than was previously assumed,” said WWF Finland’s CEO Timo Tanninen. “We hope that this year’s massive Earth Hour event will encourage politicians to take the bull by the horns when they meet at the UN climate summit in Copenhagen in December and create a new global climate agreement leading to significant reductions in emissions.”
