World’s Iconic Buildings Go Dark for “Earth Hour” | Via
Dozens of other iconic landmarks around the world, including the Parthenon in Greece, the Golden Gate Bridge in California and Australia’s Sydney Harbor Bridge, participated in the event, sponsored by the World Wildlife Fund (WWF).
The first Earth Hour took place in Sydney eight years ago to raise money for the Great Barrier Reef.
This year was expected to be the biggest event yet, with participants in an estimated 7,000 cities around the world switching off their lights for a full hour, according to WWF.
