Last week, the science journal published a paper outlining the impact of light pollution. Between 2011 and 2022, scientists spotted fewer stars with your naked eye each passing year. They noted that the skies got brighter by about 10% every year. And this increased radiance emanating from artificial lights, called sky glow, is a problem. According to one report in the Cambridge Press, light pollution directly costs the country, which is the US, at least a billion dollars a year on electricity charges.
