Light Pollution Introductory Slide Deck

The Effects of Light Pollution on Our Rivers and Lakes

Light pollution is unwanted, inappropriate, or excessive artificial light that can affect wildlife behavior, human health, and environmental quality. It can disrupt the natural behaviors and processes of aquatic life, interfere with nocturnal wildlife, and impact human health by disrupting circadian rhythms. Light pollution can also contribute to climate change by wasting energy. To prevent light pollution, simple changes can be made, such as installing light shields, choosing lower-wattage bulbs, and turning off unnecessary lights.
