Ecosystems Need Dark Skies
Presented by Dr. James Lowenthal
Wednesday, May 15, 2019 – 7 pm
Tolman Auditorium, Springfield Science Museum
Plants and animals depend on Earth’s daily cycle of light and dark to govern life-sustaining behaviors such as reproduction, nourishment, sleep and protection from predators. Humans need the natural day/night cycle for good health as well. A growing number of scientists, advocates and conservationists say the naturally dark sky should be protected as a valuable resource that helps keep humans connected to their shared history of stars while aiding plants, animals and insects that evolved without artificial illumination.
Dr. Lowenthal is a professor of astronomy at Smith College, Northampton. He is the Vice President of the American Astronomical Society and within the AAS sits on the Committee on Light Pollution, Radio Interference, and Space Debris. This evening’s presentation will focus on light pollution, how it affects life, and practical ways we can minimize it for energy conservation and better health
