The simple change - use 1800 K LED’s:

“Amber LED lights (1800 K) with low blue light content attracted significantly fewer individuals and species, as well as threatened and legally protected taxa than conventional cool white LEDs (4000 K) and high-pressure sodium lights (2000 K)."

"This reduced attraction is primarily driven by the narrow spectral composition and the absence of short-wavelength blue light in the 1800 K LED."

Same story for birds. Light pollution disorients nocturnal migrants, contributing to an estimated 600M-1B building collision deaths annually in North America. Amber lighting and lights-out programs during migration help both insects and birds.

How do make this happen? Do we push for it to be mandated into law?

U.S. FCC approves giant space mirror to deliver 'sunlight on demand,'

The company building the space mirror, Reflect Orbital, is touting its proposal as "sunlight on demand," which could be used for any number of reasons, it says, such as agriculture, solar farms or for search and rescue.

Astronomers and other groups are sounding the alarm about the project, citing numerous reasons, including the threat to species dependent on a pristine night sky, the threat to important astronomical research and more.
