Here’s a press release of the WWF Australia:
Tonight’s the biggest ever Earth Hour with a record 147 countries and territories are preparing to send a united message that now is the time to take action for the planet.
Hundreds of landmarks across more than 5,000 cities and towns will go dark at 8:30PM on Saturday local time, with Libya, Algeria, Bhutan and French Guinea among those participating for the first time.
Earth Hour began in 2007 as a one-city initiative in Sydney, Australia and has since grown to be the world’s largest voluntary action for the environment.
In Australia, cities across the country will go dark with 151 towns and cities signed up including, for the first time, the Torres Straight Islands, Christmas Island, and the Territories of Cocos Keeling Isles. The Prime Minister Julia Gillard has also lent her support to Earth Hour this year, saying “what began in Sydney as a simple idea to raise awareness of climate change – has become a global success.”
A number of other prominent Australians are also supporting Earth Hour this year including Sydney Lord Mayor Clover Moore, Isabel Lucas, Peter Garrett MP, Bill Granger, Miranda Kerr, Missy Higgins, Bindi Irwin, Laura Andon and Lizzy Lovette.
Around the world prominent supporters for this year’s Earth Hour include cricket legend Sachin Tendulkar, UN Secretary-General Ban Ki-moon, Greenpeace International Executive Director Kumi Naidoo, former Vice President Al Gore, The Director General of UNESCO, Irina Bokova, the President of Fiji Ratu Epeli Nailatikau, and astronaut André Kuipers who will take part in Earth Hour from the International Space Station.
