What is Earth Hour?
Earth Hour is a worldwide programme organized by the World Wide Fund for Nature to take a stand against the climate change. It was started as a lights-off event in Sidney, Australia in 2007. The event is held towards the end of March annually, encouraging people to turn off their non-necessary lights for one hour as a symbol for their commitment to the planet.
