Hong Kong is among the cities which have the largest populations in the world, but with night skies around 1,000 times brighter than globally accepted levels, it gains a bad reputation(名声) for its light pollution.

A study by Hong Kong University found that brightness levels in the southern Chinese city's popular shopping district of Tsim Sha Tsui were 1,200 times greater than the international dark sky standard.

The crowded city of 7 million people, full of residential(住宅的) high-rises, towering office blocks and neon(霓虹灯) advertisements has no laws to control outdoor lightning.

The result is that light pollution is thought to be much worse than in other large cities, including London, Sydney, Tokyo and Shanghai.

“In Hong Kong, you can't go anywhere outdoor in the evening without your eyes being blinded by this really upsetting outdoor lightning,” the light pollution survey's head Jason Pum told AFP.

“The fact that we have all this light in the sky means energy is wasted,” he said, adding that too much artificial lightning also affects nightly wildlife.

Research has suggested that light pollution can cause a number of harmful health problems in humans, including sleeplessness and headaches and can also affect body clocks and hormones(荷尔蒙).

The university's survey, the result of five million measurements taken from points across the city, was released just days before the start of the yearly Earth Hour event, organized by the World Wildlife Fund.

People around the world will be encouraged to turn off the lights for an hour on Saturday night to advertise climate change. Last year, a number of Hong Kong's major buildings along Victoria Harbour went dark to mark Earth Hour.

“Anyway, we should do our best to reduce the amount of lightning and suit it to the benefit of the environment.”
