Earth Hour is a global event taking place this Saturday, the 28th March 2009. At 8.30pm around the world, people, businesses and iconic buildings around the world will switch off their lights for an hour, making a statement to the world’s governments for more urgent and effective action on global warming.

We’re working with the WWF to get the word out to bloggers – starting a conversation about Earth Hour and encouraging people to sign up to show their support.

If you have a blog, it would be really fantastic if you could blog about Earth Hour yourself – and even better if you could ask your readers to get involved telling their colleagues, friends and family too. You could embed the nifty light switch widget (you can see it on the top right of our site), or use one of the videos or banners that are available.

Every contribution, no matter how small you think it might be (even re-tweeting this post would help!), is important, so please help us and show your support.

N.B. If you’re not in the UK, you can still help the global campaign – they even have their own set of widgets.
