In addition to causing breast cancer, light pollution has now been shown to affect the atmospheric chemistry at night in urban regions, increasing the next day air pollution by up to 5%. Ignoring any deleterious effect on astronomy, why are we being idiots on this? Why can't people aim lights correctly so they don't miss well over 50% of the thing they want to light? Why can't we understand if you want to light something on the ground, you can't do it by sending light up?
