Earth Hour

Earth Hour is a campaign run by the WWF. They are encouraging everyone to turn off their lights for one hour to help support their mission to promote the need for urgent action to tackle climate change and protect the natural world.

You can take part in Earth Hour on Saturday 26 March 2011 at 8.30pm and join in with millions of others who are turning off lights (including some iconic landmarks).

For more information about Earth Hour see the WFF website.
