#104 Opinion | Is the Evening Sky Doomed? - The New York Times 21.8.2019
https://www.nytimes.com/2019/08/17/opinion/sunday/light-pollution.html
"I think there is even an existential cost. A dark night sky, unpolluted by artificial light and thousands of artificial satellites, serves as a visceral reminder that we are part of something unfathomably large, that our petty differences on this tiny speck of a planet are ultimately insignificant. In the face of the universe, human arrogance is absurd."

Linnut eivät törmää vain suuriin lasi- ja valokeskittymiin (pilvenpiirtäjät) vaan niiden hajautumiseen (asuinrakennukset). Artikkelissa ei mainintaa muista seinämäisistä lasirakenteista (kaiteet, pysäkit, meluesteet), ja kysymys lasista itsestään nähdään vähempänä kuin keinovalo. Rakennetut ympäristöt myös nähdään ongelmana pelkästään lintujen muuton kannalta.
