It's not like nothing can be done about light pollution. For example Germany has a law about light pollution, and it shows on this map. It less polluted than its neighbours, although it has higher population density and urbanization level.

I think the problem is that all the people who knew why the lighting ordinances were passed retired. Because Prescott doesn’t have Lowell Observatory in the city limits the reasons behind the ordinances were forgotten.
Blue-white outdoor lighting should be prosecuted as a public nuisance.
This place in Kazakhstan is lit! https://www.lightpollutionmap.info/#zoom=5.62&lat=48.7573&lo...
Oil field or something? https://www.google.com/maps/place/48%C2%B014'12.6%22N+57%C2%...

What is the law? What are people legally required to do?
Probably the most noticable change in recent years is the replacement of mercury-vapor streetlights with the yellow-orange sodium-vapor lights, or with orangish LEDs (although some use blueish LEDs that are not that great for light pollution). In terms of actual legal requirements, Bavaria prohibits sky beams/searchlights directed upwards, and the illumination of facades of public buildings between 11pm and morning.

Is it a rendering artifact or something, that the left half of the United States is entirely darker than the right half? Like a line was drawn down the middle.
Nope, if you look at a population density map it has the same line. I'm not at all sure why that's true, geographically.
I’d love to see an animation of this.

I assume it must be. The incredibly bright spots at Keene, North Dakota and the northern edge of Alaska have similar low population/bright spots.
