At 8:30 PM on Saturday 26th March 2011, lights will switch off around the globe for Earth Hour  and people will commit to actions that go beyond the hour.
Earth Hour started in 2007 in Sydney, Australia when 2.2 million individuals and more than 2,000 businesses turned their lights off for one hour to take a stand against climate change. Only a year later and Earth Hour had become a global sustainability movement with more than 50 million people across 35 countries/territories participating. Global landmarks such as the Sydney Harbor Bridge, CN Tower in Toronto, Golden Gate Bridge in San Francisco, and Rome’s Colosseum, all stood in darkness, as symbols of hope for a cause that grows more urgent by the hour.
With Earth Hour almost upon us, our thoughts are with the people of Japan during this incredibly challenging and sad time for their country.
