Light pollution: an environmental issue that affects us all
Before humans invented fire, the only things that lit up the night were transient: the moon, the stars, and bioluminescent life (mostly fireflies). But as advances in technology have made it cheaper and easier for us to light up our world, artificial light has pervaded urban, suburban and rural habitats alike -- where it often shines all night, all year-round.
In this event, 2019 Switzer Fellow Avalon C.S. Owens will lead a discussion of how light pollution impacts people and the planet, and go over current recommendations of easy, energy-saving ways to protect the night. (Spoiler: The most important step is realizing that it is a problem in the first place!) She will conclude by talking about her Ph.D. research into effects of light pollution on fireflies, charismatic flagship species capable of inspiring profound environmental progress.
