BEIJING--Lights went out for an hour at some famous landmarks and homes all over the world on March 28 for Earth Hour 2010. It is a global event created by the WWF(World Wildlife Fund) to make people pay more attention to climate change.

From the Sydney Opera House and Harbor Bridge to the Eiffel Tower in Pari sand London’s Houses of Parliament, lights went out to encourage people to cut energy use.

Organizers said the action showed that a great number of people wanted the government to take measures to fight global warming by the end of 2010. "We have been dreaming of a new climate deal for a long time," said Kim Carstensen, head of a global climate organization. "Now we’re no longer alone with the dream. We’re sharing it with all these people turning off their lights," he said.

Australia first held Earth Hour in 2007 and it went global in 2008, attracting 50 million people. WWF is hoping one billion people from 1,000 cities in nearly 90 countries will take part in the event.

Oriental Pearl Tower in Shanghai, the Bird’s Nest in Beijing and many other famous buildings in China also joined in this event.
