In Humboldt we are not new to protecting our environment, but have you ever thought about protecting the night sky from pollution? When nighttime light spills outside of areas we want to illuminate, it becomes light pollution. Bright lights left on at night can disrupt the circadian rhythms of people as well as urban-dwelling and migrating birds, bats, and even aquatic animals, particularly in rivers, estuaries and coastal areas.

Ruskin Hartley, CEO of DarkSky International, shares how his organization is helping to ensure that light is used respectfully and responsibly around the world. Join us for this discussion of the basics of light pollution.
