Some buildings in Shanghai’s Pudong area last night took part in the Earth Hour global environmental campaign by turning off their lights for an hour in an effort to draw awareness to climate change and light pollution.
Landmarks across the globe went dark from 8:30 p.m. to 9:30 p.m. local time on Saturday to participate in the campaign first held by Sydney, Australia in 2007 as a response to research revealing the negative implications of light pollution.

A study released by the University of Hong Kong last year indicated that the city suffers from the worst light pollution in the entire world, specifically the tourist district Tsim Sha Tsui, which is about 1,200 times brighter than the average dark sky.
Light pollution is believed to have negative effects on health and in the environment leading to worker fatigue, ecosystem disturbance and energy consumption.
