I remember when they had a potential solution for the street lights. I couldn't recall the details. Somehow the solution is supposed to direct the light downwards and to prevent the upwards direction with ambient light. Also there's the problem of pollution in major cities.
The IDA was founded in 1988 “to preserve and protect the nighttime environment and our heritage of dark skies through environmentally responsible outdoor lighting.” Many of the city-based groups have mobilized around the issue of streetlights — specifically, the large streetlight replacement programs that are converting all metal halide, mercury vapor, and high-pressure sodium luminaires to light-emitting diodes (LEDs). But not all LEDs are created equal. To the dismay of dark-sky activists and some city residents, many cities installed ultra-bright LEDs that emit a blue wavelength similar to that of the daytime sky. Selecting warmer colors of LEDs would help the stars shine through, but groups like the IDA would also like to see streetlights that are shielded and dimmable and backed up by a robust city lighting ordinance.

Isaiah 6:5
“Woe to me!” I cried. “I am ruined! For I am a man of unclean lips, and I live among a people of unclean lips, and my eyes have seen the King, the Lord Almighty.”
