The world celebrates Earth Hour by turning off the lights and lighting candles. The lights went out as part of a global movement encouraging countries to turn off their lights at 08:30 pm local time - for an hour.
Prominent landmarks around the world participated in the Earth Hour activities, such as the London Eye, the four Tate museums in London, Liverpool and Cornwall. Most of the ministries, institutions, and governmental, semi-governmental and private bodies in the State of Qatar also participate in the global event.
