I’ve been complaining about this in my area for years. Where I live, the main problem right now is private property owners (mostly condos and commercial real estate, not so much private homes), refusing to put lids (or hats) on their security lights to point it down. We’ve lost half the night sky since 2011 in my area due to these lights going up. In various discussions, I’ve been informed that the insurance companies are behind this problem. If we could convince them to mandate night-protective lighting (with metal hats pointing the light down) this would return our night skies.
