The Meaning of Darkness: How Light at Night Has Transformed Our World

Seventy percent of mammal species are nocturnal and require the night to survive. Humans need the night to revive. Ken Walczak of the Adler Planetarium will examine the impact of altering the day/night cycle on our health, safety, ecology, environment, and future.

A three-course lunch is served on Mondays at noon. Doors open at 11:30 a.m. for check-in and socializing. Reservations required, CLICK HERE or call the office at 708-386-2729.
