Hong Kong dims as it embraces Earth Hour
WWF welcomes 'commitment to change' but professor criticises event as 'harmful gimmick'
For the fifth year in a row, Hong Kong's famous skyline dimmed last night as residents embraced the green mantra of Earth Hour.
But for one university professor who specialises in sustainable development, it was a chance to protest against what he called a gimmick that did more harm than good.
"There are more than 8,700 hours in a year. What can one hour contribute?" said Professor Edward Ng Yan-yung from Chinese University's school of architecture. "Some say the event raises awareness, but my take is: what awareness will it bring? The dilemma is that one goes away thinking that one has already saved the earth."
For one hour from 8.30pm, thousands of buildings switched off their lights to mark the initiative, which Hong Kong first adopted in 2009. Organised by the conservation body WWF, Earth Hour debuted in Sydney in 2007 and has since spread to 152 countries.
Ng says he never turns on his office light at night because he works mainly on his computer and has a desk lamp that he uses sparingly.
"But I will turn on my office light during Earth Hour, just to remind myself what I have been doing for the rest of the year."
A WWF-Hong Kong spokeswoman says it was a symbolic event aimed at getting people to think about the ecological impact they make on the world.
