Turn off your lights for one hour at 8pm March 29 (that’s tomorrow) “to deliver a powerful message about the need for action on global warming.”

Households and businesses around the world are urged to turn off their lights and non-essential electrical appliances for one hour in an international event called Earth Hour 2008.

Earth Hour started out in Sydney, Australia between 7:30 p.m. and 8:30 p.m. on 31 March 2007. That year it was a local event in Australia, this year they are going bigger than ever. Over 11,900 businesses and over 200,000 individuals have signed up to take part in this event. Cities worldwide like Dubai (UAE), Bangkok (Thailand), Örebro (Sweden), San Francisco (USA), Toronto (Canada) and many others will also participate.

It is indeed a worthy cause that should be supported. But one can’t stop from wondering if this, one hour, of turning down your electricity, is all we in the developed world is willing to do? Or like Al Gore said:

“I can’t understand why there aren’t rings of young people blocking bulldozers and preventing them from constructing coal-fired power stations.”
