HK night light pollution
under the spotlight

HONG KONG — One of the world’s most densely built-up and populated metropolises, Hong Kong is also one of the most brightly lit.

From bustling streets bathed in an array of neon signs to gargantuan spotlight-strewn advertising hoardings to massed light-specked skyscrapers twinkling off the waters of Victoria harbor at night, the glow over the sleepless city makes it difficult to glimpse stars in the night sky.

In an era of growing green consciousness and global warming fears, environmentalists are increasingly critical of this ostentatious display, calling it as unnecessary and wasteful.

"The trend is getting worse and worse," said Hahn Chu, the environmental affairs manager for Friends of the Earth: "Hong Kong always thinks the brighter things are, the more prosperous we seem, but people often forget that we’re wasting energy."

While Hong Kong doesn’t have compulsory measures for lights out, a recent public opinion poll on energy conservation by the Council for Sustainable Development found 71 percent of over 80,000 people backed turning off neon lights in the small hours.

In 2008, the city’s environmental protection department received some 50 complaints about light pollution, up from the 40 cases received in 2007, with neon signs posing a growing nuisance for the public.

A massive neon sign advertising luxury brand Prada was found to be one of the worst offenders in an online poll, spilling intense white light onto a near-deserted Central street until till 5 am every day.

"This is flamboyant wastage and creates light pollution," one respondent was quoted as saying.
