The Journey Back to the Stars: Limiting the Harmful Effects of Light Pollution


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.
