Last night I attended an Audubon meeting here in Winona. The topic was light pollution. We watched a 35 minute documentary called Lights Out In Texas. Next we heard from a Winona State Professor who studies astronomy specifically when two objects collide in space. She also knows about light pollution because twenty years ago she had a student who was interested in light pollution in Winona and he also happened to have a pilot license. She showed us pictures of light pollution over the last five decades. Light pollution for the most part is worse. According to her figures, 60 to 80 percent of today's children will never see the Milky Way because of light pollution. Winona State has done much to reduce light pollution. They replaced their outdoor lights with lights that shine only down. Also, the lights go dim unless someone walking by triggers the light to come on fully. The residential parts of Winona are fairly dark. The lightest places are automotive dealerships and big box stores like Walmart and Target. According to her, light pollution is better but there is still room for improvement.
