Please join me on Friday, November 14 at 6 pm at Heller Nature Center to see the film City Dark. The movie explores the implications of a globe glittering with lights — including increased cancer rates, and a generation of kids who can’t see the universe above. The film features stunning astrophotography, and an eclectic cast of scientists, philosophers, historians, and lighting designers. The Highland Park screening is free and open to the public, and is co-sponsored by the Natural Resources Commission and the Park District.
