Earth Hour is a worldwide movement for the planet organized by the World Wide Fund for Nature (WWF). Each year, from 8:30 to 9:30 p.m. on the last Saturday in March, households and businesses are encouraged to turn off their lights as a symbol for their commitment to the planet. Many iconic landmarks around the world participated in this year’s Earth Hour this past weekend. Here are some amazing pictures of the iconic landmarks that went dark.
