This presentation is part of the Cape Perpetua Speaker Series, hosted by the Cape Perpetua Collaborative.
For billions of years, night on Earth 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 this planet is now liberally colonized with artificial light. This has dire ecological consequences for plants, birds, fish, amphibians, mammals and other wildlife. Light at night also impacts human health, safety and culture. In this talk, we will delve into the importance of darkness for nocturnal wildlife, from migrating birds to sea turtles to intertidal invertebrates and nesting seabirds. We will explore some of the night’s wondrous mysteries and the local and international effort to preserve dark skies in both cities and wild places, from deserts to coastlines.
