Brisbane, Australia, Before Earth Hour

The city lights of Brisbane--Australia's third most populous city--create blurred pillars of color on the Brisbane River on March 29, 2008.

In March 2008 Brisbane was among more than 400 participating cities that turned off its lights (see next photo) to celebrate Earth Hour, a movement started in Sydney in 2007 to show commitment toward slowing the effects of global warming. In 2009, 2,712 cities, towns, and municipalities in 83 countries have signed up to participate in Earth Hour on March 28 from 8:30 to 9:30 p.m. local time.
