Robert Sullivan, Retired, Argonne National Laboratory will present on the harmful effects of light pollution on wildlife and human health, and what you and your local government can do to reduce the impacts.
Life on Earth evolved in conditions subject to only natural sources of light and is adapted to these natural lighting sources and cycles. Many plants and animals depend on natural cycles of light and darkness for optimal health and even survival. Evidence is mounting that artificial light at night (ALAN) affects the behavior, health, and abundance of various living creatures, thereby disrupting natural ecological processes. This presentation discusses how unwanted ALAN—light pollution—harms wildlife and affects human health and well-being. Best management practices for reducing negative impacts of ALAN are also presented.
