Here’s One Type of Pollution You Probably Haven’t Heard Of Yet

By Richard K. Noots

Something many people may not know is that our starry night sky isn’t what it used to be. The reason is due to light pollution, and it’s caused by our overabundance of lights. Obvious reason, but where is the real harm? It turns out, not only do many animals rely on the night sky, this occurrence is probably disrupting our circadian rhythm. This, in turn causes many stress-related issues, which (of course) includes cancer. Give the video a watch, and think about how our early ancestors may have seen the night sky. I wonder, will we ever get a chance to see it like they did?
