     On March 27, Saturday evening, people all over the world once again turned their lights off for an hour
to help fight against global climate changes and give the world a brighter future.
     For Earth Hour 2010, many best-known buildings went dark from 8:30 to 9: 30 local time, such as the
Eiffel Tower, Big Ben, Sydney's Opera House and Beijing's Forbidden City, etc. Millions of businesses and
homes around the world also turned off their lights.
     Some 4, 000 cities in more than 120 countries volunteered to turn off Saturday to reduce energy
consumption (能量消耗). "We have everyone from Casablanca to the camps of Namibia and Tanzania taking
part," said Greg Bourne, CEO of WWF (World Wildlife Fund) in Australia, which started Earth Hour.
     Earth Hour began in Sydney, Australia, in 2007. In 2008, the event turned into an international one, which
has drawn the participation of hundreds of towns and cities worldwide. Now in its fourth year, more and
more cities from the world took part in Earth Hour as a show of support for action against global warming.
     In a WWF survey after Earth Hour 2009, 80 million U.S. citizens said they had participated, according to
Ann. "Earth Hour has always been an event about families and individuals as well," Ann said, "and it's really
about Americans and people all over the world standing up and saying climate change is real and we need to
do something about it now."
     However, Earth Hour's energy-saving influence is limited. But WWF says that Earth Hour's real value is
symbolic (象征的).
