Tonight is Earth Hour – at 8.30pm locally, wherever you are.

It’s started already – go to Flickr to see the photos of people taking part in New Zealand, Fiji, etc… Look at the YouTube channel for more info. Visit the main site and sign up to take part yourself or just share in the activity.

It’s a lovely, collective piece of passion for mother earth, organised by the WWF and friends.

And it’ll be interesting to go back tomorrow and see all the images, video, etc. from people involved – I wish there was a live satellite feed to show the lights going out – maybe there is and I just didn’t spot it.
