[120.06] What Astronomers and the AAS Need to be Doing to Curb Light Pollution

D. W. E. Green (Harvard-Smithsonian CfA)

Astronomers and especially the AAS are doing apalling little in the war on light pollution. This is quite surprising, considering that optical groundbased astronomy may become nearly extinct in the 21st century if we don't get more serious about the loss of our night skies to artificial lighting. Part of the blame must be placed on astronomers throughout the 20th century (particularly before 1980), as very few of them seem to have set an example by starting an early crusade against bad outdoor night lighting (save for a handful of important individuals near large U.S. observatories, and a few connected with smaller observatories); this apathy of earlier generations of astronomers fueled the current general apathy within the AAS and aided the opening of the floodgates in terms of the disastrous lighting situation now upon us in terms of drowning out the night sky. There are possible solutions, and they need to be discussed and acted upon quickly. For example, the AAS should require that all members include a useful amount (say, $30) in annual membership fees to be directly transmitted to the International Dark Sky Association, and the AAS should make constant visible strides to educate the public and government officials of the absolute need to reduce outdoor lighting levels and to fully shield all outdoor lighting. There are many other areas of research into outdoor lighting that the AAS should fund or officially/strongly support, so that the astronomical community can better be educated (and can better educate the public) on the evils of bad and thoughtless outdoor-lighting practices; such research includes developing a comprehensive database of national statistics on numbers and types of different outdoor lamps, as a function of time (thus, historical), and also a comprehensive database including all local, state, and federal lighting laws and ordinances together with legal court cases (and their outcomes) involving outdoor night lighting. And professional astronomers realistically have an obligation to their colleagues to discuss the problems of (and solutions to) light pollution at any and all talks concerning astronomy or astrophysics to the general public. All general astronomy textbooks and school/college courses should have considerable (not merely token) space and time devoted to the problem of bad outdoor-lighting practices.
