Enacting curfews at 10 p.m. or at the conclusion of an event lessen complaints from nearby residents. Undeveloped parks, forests, and fish and wildlife management areas should be maintained in a natural state, where possible. Wildlife Sky glow from cities disorients migrating birds and is responsible for high mortality rates in first-year migrants. Bright, glary lighting on tall towers leads to impact, and thereby large numbers of injuries and deaths of birds. Light pollution reduces the suitable area of feeding habitat for owls and other night-hunting birds.
Light pollution produces disorientation and leads to the deaths of various reptiles and amphibians.
Astronomy Most sky glow is avoidable. Then, reflected light from appropriate lighting will be the cause of a substantially reduced sky glow. In suburban areas of cities where anti-light pollution ordinances have been adopted, the Milky Way is visible. This could very likely occur in many other suburban areas as well. Energy Waste Excessive levels of light, even with cutoff luminaires, contribute to light pollution since some portion of the light will be reflected in various directions.
