Earth Hour 2009 motivated millions and millions of people and businesses to shut off their lights to support the fight against global warming. The demonstration is partially sponsored by the World Wildlife Fund. Many internationally known landmarks went dark last night at 8:30 pm (regardless of timezone). The Sydney Opera House, Giza Pyramids, Roman Coliseum, Eiffel Tower, Golden Gate Bridge, Empire State Building and the Las Vegas Strip are just a few of the many dim historical sites.
