I wrote a paper on light pollution in 1972. The solutions aren’t necessarily what people think—most involve fixture design that direct light downward where it is needed and limiting the amount going skyward.
Exactly. You don’t have to eliminate the lights, just direct the light where it’s needed.
[[limiting the amount going skyward.]]
Why limit what goes skyward? What purpose could there be in limiting skyward light?
dear stormer,
re; your 1972 report, a collegiate class grade-inducing organ, i imagine.
Roadways reflect moonlight, therefore, any ‘downward’ directed artificial light will be reflected, as well.
Any urban structure, including store displays, has reflected artificial light.
One thing that you might not have considered in your conglomeration of ‘light pollution’ ...
according to U.S. Code, any U.S. Flag that is still on the flagpole after sunset, must be illuminated. I guess that shoots down your ‘downward-directed emanation of light’, doesn’t it?
