As part of a campaign to encourage environmental awareness well before Earth Day on April 22, the United Nations and the World Wildlife Fund are urging people around the globe to turn off their lights for one hour from 8:30 to 9:30 pm local time on March 29, 2014.

The campaign, called “Earth Hour,” invites participants to “celebrate their commitment to the planet.”
