It's no secret that our world is getting brighter, especially at night, as more artificial light is added to our environment. And that expanding brightness is having an effect, often a negative ecological impact on wildlife.

Professor Jesse Barber with Boise State University's Department of Biological Sciences joined Idaho Matters to talk more.
