This is proof that light pollution can be reversed. Dark areas can be preserved AND reclaimed. France has national lighting ordinances and laws to enforce good lighting.

I was inspired this weekend at the #JMU campus that our efforts can have lasting impacts. Dr. Bogard advocated for the #naturalnight here during his time there as a professor. These clever lamps have a semi-recessed light, with no sides to keep #lightpollution from escaping UP from the sides.

Have you ever wondered how a #shearwater fledgling flies from its nest to the places where they are grounded by #LightPollution? We've used GPSs with remote download to track their flights & published this paper doi.org/10.3389/fevo... #seabirds #seabirdersaturday
