It has been called “the world’s largest mass participation event
ever.” On March 27, monuments all over the world – from the
Eiffel Tower to Rio’s Corcovado, from the pyramids at Giza to
the British houses of Parliament – will go dark. Skylines from
Shanghai to Moscow to the Las Vegas strip will flicker out at
8:30 p.m. local time. And millions of people will gather by
candlelight. It’s all part of Earth Hour, a campaign by WWF, now
in its forth year, to show action on climate change “is not
about what country you’re from. It’s about what your planet
you’re from.” Last year, a billion people and 4,000 cities
worldwide participated in the campaign “Earth Hour is a way for
the citizens of the world to send a clear message: they want
action on climate change,” said U.N. Secretary General Ban Ki-
Moon. Click here to learn more.
