Four ways to curb light pollution, save bugs Insects have experienced global declines. Flipping the switch can help.
Writing in the scientific journal Biological Conservation, Brett Seymoure, the Grossman Family Postdoctoral Fellow of the Living Earth Collaborative at Washington University in St. Louis, and his collaborators reviewed 229 studies to document the myriad ways that light alters the living environment such that insects are unable to carry out crucial biological functions. “Artificial light at night is human-caused lighting — ranging from streetlights to gas flares from oil extraction,” Seymoure said. “It can affect insects in pretty much every imaginable part of their lives.”
