Light Pollution

Friday, October 3, 2008Light Pollution

If you make a habit of looking at the stars, you've probably noticed the night sky looks a lot different from out in the country than it does within city limits. What you're noticing in urban areas is called light pollution – light produced by humans that obstructs our view of the stars. It can also disrupt ecosystems, interfere with astronomical observatories, upset the sleeping patterns of animals, and even adversely affect human health. Join us this Friday when we discuss the contributing factors, and what anti-light pollution groups are doing to minimize the effects, in a conversation about light pollution. Today's show is from our archives, so we won't be taking calls this hour.
