There's good news to report in the fight to preserve the night sky! On June 16, 2009, the American Medical Association (AMA) voted unanimously to support efforts to control light pollution. What makes this new policy particularly important is that the AMA encompasses the medical societies in all 50 U.S. states and more than 120 specialty societies.
Why has the AMA, a powerful and influential group, decided to support light-pollution legislation? There are multiple reasons. First, the glare from bad lighting is a public-health hazard — especially the older you become. Glare light scattering in the eye causes loss of contrast and leads to unsafe driving conditions, much like the glare on a dirty windshield from low-angle sunlight or the high beams from an oncoming car. Second, wasted light represents unnecessary energy and CO2 production. Finally, many species (including humans) need darkness to survive and thrive.
