Why Hongkongers should turn down the lights for Earth Hour
It's time the government stopped pandering to the tourism and advertising industries and acted to limit the health impacts of light pollution on its people, writes Kylie Knott
The 10th Earth Hour, WWF's annual global campaign to switch off all non-essential lighting, will begin on Saturday, at 8.30pm.
It could not come a moment too soon.
The report found parts of the sky above Tsim Sha Tsui were 1,200 times brighter than normal. Even remote areas of the Sai Kung countryside were found to be excessively bright.
That excessive amounts of light can disrupt our biological clock and affect brain and hormone function has been well documented, so supporting the Earth Hour campaign makes particular sense to Hongkongers. What doesn't make sense, however, is the government's reluctance to introduce legislation to control external lighting, following in the footsteps of major cities such as London, New York, Sydney and Shanghai.
Instead of tackling the issue head on, the powers that be have tiptoed around it by setting up the toothless Task Force on External Lighting, which, after years of study, in 2015 opted for the soft approach of voluntary compliance instead of legislation.
It's time the government stopped pandering to the tourism and advertising industries, which say they rely on lighting for business, and take a long hard look at the bigger picture: the damage light pollution is having on Hong Kong's environment and on people's health.
"The lights are on but nobody's home" could not be a more fitting idiom.
