A diagram of different urban lighting scenarios set against a dark blue-black backdrop and starry night (represented in abstract illustrated form). First, at left, (1) Problematic urban lighting. A giant light orb casts out from a streetlamp, blinding and white, extending into much of the night sky. Next (2) A streetlamp represented with a temporal controller installed. The streetlamp stands dimmed and darkened. No stray light sheds into the night sky. Third (3) A downshielded and dimmed streetlamp. Here, the light, still a white hue, is directed to the ground and there is no upward or outward pollution. Fourth (4) A streetlamp that uses a warmed temperature bulb. Its light appears in an oranger-pinker hue. The diagram notes that the light temperature for this color must be <3000 Kelvin.
4. It's up to all of us, in this time of #biodiversityloss #climatechange & corporate governance to embrace the fact that #lightpollution is one thing we—as individuals and communities—can control.
So shield those streetlamps, choose warmer hued bulbs & #turnoffthelights! The #birds will thank you.
