Earth Hour

Earth Hour is a worldwide grass-roots movement for the planet organized by the World Wide Fund for Nature (WWF). Earth Hour engages a massive mainstream community on a broad range of environmental issues. It was started in 2009. Since then it has grown to engage more than 7000 cities and towns worldwide, and the one-hour event continues to remain the key driver of the now larger movement. The event is held worldwide and held towards the end of March annually, encouraging individuals, communities households and businesses to turn off their non-essential lights for one hour as a symbol for their commitment to the planet. Earth Hour 2013 was celebrated on March 23, 2013. Earth Hour 2014 is scheduled for Saturday, March 29, from 8:30 p.m. to 9:30 p.m. during participants' local time.

It is being celebrated in all countries including the Marina Bay Sands and Tampines Secondary School.
