Episode notes
City Nights Have Lost The Milky Way
- Light pollution turns city night skies into a hazy orange or gray, erasing the Milky Way for most urban residents.
- Exodus Chen Nonsit highlights that this is a spreading problem and frames a growing movement of 'guardians' working to restore dark skies.

- Use fully shielded fixtures that direct light downward so it illuminates sidewalks and doorways, not the sky or neighbors' windows.
- Exodus Chen Nonsit explains shielded fixtures put a solid cap on top to keep light on the ground and out of the atmosphere.

- Exodus Chen Nonsit contrasts the common belief that more light equals safety with the idea that better-directed light improves safety.
