Dark nights make spring and fall migration safer birds.
Over a billion birds die every year in the United States after colliding with windows. During spring and fall migration when birds travel at night, light pollution draws them down toward cities and in proximity of buildings.

Dark nights support fireflies and other nocturnal wildlife
Many species of nocturnal wildlife, from fireflies to glow worms, foxes to bats, salamanders to owls, rely on the dark of night to carry out their natural activities of movement, hunting, and reproducing. We can support biodiversity by eliminating unnecessary lighting.

Dark nights allow us to enjoy Northern Lights & stargazing
The Northern Lights are an incredible phenomenon that are virtually impossible to see in the presence of light pollution. When is the last time you’ve been dazzled by waves of green or the Milky Way?
