For billions of years, night on this planet was lit only by the moon and stars, and life evolved under regular cycles of bright days and dark nights. All that has changed in the last 130 years, and night on Earth is now liberally colonized with artificial light. The overabundance of light at night has dire ecological consequences for plants, birds, fish, amphibians and other wildlife, as well as for human health, safety and culture.
At this Science on Tap we will delve into the importance of darkness for nocturnal wildlife as well as for the billions of migrating birds that use starry night skies to navigate. We will explore some of the night’s wondrous mysteries, the world class dark skies that we have in southeastern Oregon, and the local and international effort to preserve dark skies in both cities and wild places.
