I don't normally do this, but this is a movement I feel strongly about. Pardon my shill ...

On 31 March 2007, 2.2 million people and 2100 Sydney businesses turned off their lights for one hour - Earth Hour. If the greenhouse reduction achieved in the Sydney CBD during Earth Hour was sustained for a year, it would be equivalent to taking 48,616 cars off the road for a year.

With Sydney icons like the Harbour Bridge and Opera House turning their lights off, and unique events such as weddings by candlelight, the world took notice. Inspired by the collective effort of millions of Sydneysiders, many major global cities are joining Earth Hour in 2008, turning a symbolic event into a global movement.

So join the movement - turn your lights and power off for an hour. Created to take a stand against the greatest threat our planet has ever faced, Earth Hour uses the simple action of turning off the lights for one hour to deliver a powerful message about the need for action on global warming.

This simple act has captured the hearts and minds of people all over the world. As a result, at 8pm March 29, 2008 millions of people in some of the world’s major capital cities, including Copenhagen, Toronto, Chicago, Melbourne, Brisbane and Tel Aviv will unite and switch off for Earth Hour.

Ocean FM is trying to get everyone in Hampshire to do that this year. I think it's a very good idea.

I Pledge to turn off my lights.

that i might do the same thing!! It's a wonderful idea.

Cathy and I are planning a late dinner during the hour - doing a Broth-based fondue by candlelight. Of course, Veronica would prefer a choclate fondue, but I will sway her over with noodles.

Our family will gladly join this cause. I hope others in Finland will too. It's still winter in here 10 days from now, but because we've got triple glazed windows, that won't be a problem. Hmm... in fact I can't even turn of our heating since our house uses a district heating system. But the lights must go!

as long as I'm reminded I'll do it.
