Light Pollution Videos

We will be joined by guest speakers from the Pennsylvania chapter of DarkSky International for an informative session on the importance of reducing light pollution for bird, insect, and mammal populations, and information on what types of lighting are better or worse, and contrary to popular belief, more light isn’t always ‘safer’. We will also be joined by a representative of Bird Safe Philly to talk about the massive bird Collison on October 2, 2020, that resulted in the death of thousands of migratory birds and how it led to the Lights Out Philly initiative. Speakers: Mark Grosz, DarkSky International; Diane Turnshek, Carnegie Mellon University; Leigh Altadonna, PA Audubon Council; Bill McGeeney, DarkSky International; Jeff Buler, Penn State University; Tim Lawler, West Chester Dark Sky Committee.

The night sky is getting brighter each year, obscuring the stars from our sight. Light pollution is the cause, the excessive, obtrusive, artificial light at night that prevents us from living under a sky bright with stars. It adversely affects human health and the entire nighttime ecosystem, and can produce unsafe glare and raises our carbon footprint by wasting energy. We can limit the disruption of wildlife across Pennsylvania and restore our environmental balance with a combination of education, technology, and ordinances. Join experts in the field to learn about the dark side of light and what steps can be taken to bring back the stars.
