WWF are attempting to reach a target of 1 billion "votes for Earth", which will be presented to world leaders at the Global Climate Change Conference in Copenhagen 2009.
In London, the famous Coca Cola sign in Piccadilly Circus will be switched off for only the third time since the Second World War. Other famous London landmarks taking part in Earth Hour include Nelson's Column in Trafalgar Square; the London Eye; the National Gallery; the V&A Museum and the National Theatre. There will be a demonstration of the eco friendly wind powered lights on Primrose Hill, and countless other people, businesses and schools will be joining in too.
Earth Hour began in Sydney in 2007, when 2.2 million homes and businesses switched off their lights for one hour. In 2008 the message had grown into a global sustainability movement, with 50 million people switching off their lights. Global landmarks such as the Golden Gate Bridge in San Francisco, Rome's Coliseum, the Sydney Opera House and the Coca Cola billboard in Times Square all stood in darkness.
Currently 2,848 cities and towns in 84 countries have committed to the event. To register your vote simply sign up on the Earth Hour website and switch of your lights this Saturday evening.
