Started by WWF-Australia in 2007, Earth Hour encourages everyone to show their support for stopping climate change by turning off their lights for one hour on the last Saturday of every March. Since its inception, Earth Hour has helped raise awareness about climate change and overconsumption, and has inspired people around the world to work together for a better future.
