Dark Sky Film & Panel Discussion
Friday, June 27th at 4pm in the Frick Fine Arts Theater
Dark skies are essential not only for preserving the natural beauty of the night but also for safeguarding the health of both humans and the planet. Excessive artificial light disrupts human circadian rhythms, leading to sleep disorders, increased stress, and a higher risk of chronic illnesses such as obesity and heart disease. For wildlife, light pollution interferes with natural behaviors like migration, reproduction, and feeding, threatening biodiversity. Moreover, dark skies help reduce energy consumption and carbon emissions, contributing to climate change mitigation. Protecting our night skies is a simple yet powerful step toward a healthier, more sustainable world for all living beings.
Please join us for a fun event to wrap up pollinator month! We invite you to the beautiful Frick Fine Arts Theater to watch the documentary, Defending the Dark, followed by a panel of experts, and lively discussion over appetizers and drinks. Please RSVP so we have enough for everyone without creating unnecessary waste. We are dedicated to planetary health and do our best to host zero landfill waste events. Please RSVP here.
