A global event organised by the World Wide Fund for Nature, Earth Hour is an event on the last Saturday of March annually, requesting businesses and households to switch off their non-essential lights for one hour. This is aimed at raising the awareness of humanity towards the need to take action on Climate Change.
The first Earth Hour event was in Sydney in 2007, when 2.2 million residents of Sydney participated by turning off all non-essential lights. Following the lead by Sydney many cities followed suit and now the Earth Hour is a global event.

The supporters of the E H include Bishop Desmond Tutu, Helen Clark, the Irish Rock band the Cranberries, the Mayor of London Borin Johnson, NFL Football player Tom Brady and other celebrities.
