Earth Hour 2009

November 20th, 2009 | Category: Environment

Earth Hour started in Sydney in 2007 and is now a worldwide event taking place in 88 countries and 4000 cities around the world.

Since 2007, Earth Hour has gained worldwide support for positive action against global warming. It all began with 2.2 million people in one city using their light switches to have their say. By March 2009, hundreds of millions of people in over 4,000 cities in 88 countries officially switched off to vote for Earth.

Next year’s event will be held on Saturday the 27th March 2010.
