From The Albuquerque Tribune:
A common and unruly trespasser might finally be chained in its own yard if an Albuquerque ordinance passes.
That intruder isn’t an animal, but light, which under vague laws can legally stray from the sides of backyard floodlights into the bedrooms and living spaces of disgruntled neighbors, said Josh Skarsgard, an assistant city attorney who just finished writing a proposed light pollution ordinance.
The ordinance would clamp down on that type of light, called “light trespass.” It will make it illegal for people to have outdoor lights stronger than 75 watts – unless they are fully shielded so the light doesn’t reach other’s homes, he said.
… “If this goes through, in about three years even places like Downtown Albuquerque will be significantly changed,” Skarsgard said. “People will be able to see more shooting stars, the Milky Way, the Big Dipper – all the things we used to see when we were kids on camping trips. You’ll even be able to see most of that Downtown. That’s the plan.”
Four backyard flood lights downslope distract from NewMexiKen’s view of the city lights. And I could read in bed by the light from the motion-activated floodlight in the driveway across the street. Why don’t people point these things toward the ground?
People laugh at the idea of light pollution, but it is a serious problem for the flora and fauna and people as well. In Tucson, light pollution is especially a problem for the astronomers of Southern Arizona.
