International Dark Sky Week is a week where stargazers spread awareness of the effects of light pollution a night sky. Light pollution is the process of wasting light in any form. Solutions “include turning off unnecessary lights and putting shields on streetlights to direct beams downward.”
“Start thinking of a photon as a potential pollutant,” said Michael Justice, a behavioral ecologist who studies how artificial light affects insects. “Much like a chemical spill or gas leak, the photons being used to light your porch and street can unintentionally leak into surrounding areas and affect the local ecology at every level from plants to apex predators.”
In the last 100 years, the whole history of natural light has been significantly diminished. The sky used to be lit by stars, the moon, planets, and the Milky Way. Now artificial light serves as that. Come on people, stop wasting light!
