Light pollution is all around us is and is most unfortunately part of the industrialized world. It wreaks havoc in the ability to observe the skies and has many other adverse effects towards plants and animal life! What most people do not realize is that with some common sense and decent lighting fixtures a lot of the environmental damage can be undone, nearly immediately. It takes decades to clean up river water, soil or atmosphere.... light pollution is the only environmental problem that can really be fixed overnight, with the flip of the switch.
Having a sound lighting policy is beneficial for all. It saves money and conserves our heritage of the night sky.
