Houses and businesses across Asia turned off power on Saturday in support of the so-called "Earth Hour". In Sydney, ferries blew their horns as the lights went out on the Sydney Opera House. China's "Earth Hour" kicked off on Saturday night with the tallest building in the capital Beijing - Tower 3 of the China World Trade Centre - turning off its lights. In India, lights at the India Gate were turned off and lit balloons released as a crowd holding candles watched. In Indonesia, the lights on several landmarks, were also turned off or dimmed, and in the Vietnamese capital Hanoi, young people gathered outside the city's opera house holding candles as lights went off.
