🇭🇰 Hong Kong light pollution ruins residents' sleep

Summary

Hong Kong's dazzling skyline, illuminated by billboards and neon lights, is a major attraction, but it also causes light pollution. A study by the University of Hong Kong found the city's light levels to be among the highest globally, disturbing residents' sleep and well-being. Despite a voluntary charter encouraging businesses to reduce lighting at night, critics argue it's insufficient. While over 4,800 properties have signed up, the lack of mandatory regulations means the bright lights of the city continue to shine, with activists like Zoe Chow pushing for change.
