Piece Description

Utah's national parks provide some of the last places on Earth to see the Milky Way because of urban sprawl and light pollution. Since 1999, the National Park Service's Night Sky Team has been measuring night skies and working with nearby communities to use outdoor lighting more effectively. Darkness is not only important for foraging wildlife but also for humans, as health research has increasingly shown.

Great!

I've been trying for a long time to explain to my neighbors that light at night is bad and why. Now I've got some new arguments. One of mine, which you haven't mentioned, is about moths: light attracts too many of them to lit houses, which is gross, and deprives the neighborhood of those useful critters, which is bad for the ecosystem.
Thank you!
