Earth Hour - spread the word!

Just under two years ago in Sydney, Australia, a global movement was born. By switching off its lights for one hour to draw attention to the issue of climate crisis, Sydney created Earth Hour. Now adopted by the WWF, Earth Hour had grown by 2008 to include 370 cities and an estimated 50 million people Worldwide; in Australia, it is claimed that 58% of adults took part. Now support is being gathered for Earth Hour 2009, which in the UK will take place from 8.30 to 9.30 pm on Saturday 28th March.

Last year my household took part, having stumbled across it thanks to Google's black screen. It was easy, it was fun, and we're planning to do it again. The WWF wants to encourage as many individuals and businesses as possible to join in and already over 680 cities from 75 countries have signed up, including my home town of Reading.

There's loads of good stuff on WWF's website, including an inspiring video and a toolkit. All you have to do is switch off your lights for an hour - but businesses that close for the weekend can make an even bigger statement by switching off from Friday to Monday. A quick look at the photos here will demonstrate just how beneficial that could be.
