Light pollution is the story many of us are dealing with but a very few talk about it. On a long-term project I’m documenting the impact of artificial lights and the value of natural nights for human and other species. For most of human history, the night sky was an essential part of our nature. Now most of humanity lives under intersecting domes of skyglow from overlit cities. But there is more this. Now science revealed that light pollution, specially exposure to blue light at night, affects human body both psychologically and physiologically. Search natgeo.com for light pollution to read our @natgeo story “Light pollution is getting worse, and Earth is paying the price”.⁣ #saveournightsky #lightpollution #losangeles」6月2日 10時02分
