Earth Hour – Saturday 23 March

WWF’s Earth Hour - which takes place on Saturday 23 March 2013 at 20.30 is a time for friends and families to show their support for the planet by switching off the lights for one hour.

Last year’s Earth Hour was the biggest yet and saw a staggering 6,950 towns and cities in more than 152 countries take part. An estimated eight million Brits will be joining in for the world’s biggest switch-off this year.

From a single domestic light bulb to giant iconic illuminations such as Big Ben, the Taj Mahal and the Sydney Opera House, Earth Hour demonstrates a determination to help protect the planet.

To celebrate this year’s Earth Hour, WWF has teamed up with actress Miranda Richardson, TV presenter Kevin McCloud and comedian Alistair McGowan to record exclusive versions of Rudyard Kipling’s famous Just So stories. The exclusive audiobooks have been recorded for families to listen by candlelight during the world's biggest switch-off.

Eight of the classic childhood stories are free to download, including favourites such as How the Camel Got His Hump and How the Leopard Got His Spots.
