Light Pollution
Posted by: Cicero
When asked "what sort of pollution worries you the most", I said "light pollution from all the rural living city hipsters too scared to turn their fucking lights off". When I go out into the "country", I expect to see stars, not your fucking stadium lights because you're too big of a pussy to just by a gun and leave the porchlight on.
The maps of the artificial night sky brightness at zenith at sea level allow to compare levels of light pollution in the atmosphere, to recognize more and less polluted areas and to identify the more polluting districts and the bigger sources.

Where other places greet the night by lighting up their streets and tourist attractions, this one goes the other way—low-energy sodium lamps are shielded from above, and household lights must face down, not up. The purpose: to bring out the stars.
