Philadelphia has dimmed its skyline after a 'mass collision' killed [1000's of birds]

Fascinating read.

There's a move to darken the night sky in the Uk too, but its a bit different.
Our street old lamps shine up almost as much as down, creating a glow over towns and cities.
So they are being replaced with ones that focus down only.

As you say a win win, less energy wasted, less confusion for animals, and we should be able to see the stars better eventually.

When I lived in the high desert, with far less "light pollution", seeing the night sky was a real plus. It's part of staying in touch with nature.
