ENSC 13300 Lecture Notes - Lecture 8: Gisele Bündchen, Light Pollution, Seasonal Affective Disorder
Document Summary
Light pollution is excessive, misdirected or inappropriate outdoor lighting. Too much of light pollution washes out view of the universe, result in increase in the energy consumption, interferes with astronomical research, disrupts ecosystems, affects the health and safety of humans and wildlife. It may surprise you to know that light pollution can have as great an impact on the planet as levels of carbon monoxide and other airborne pollutants. When most people talk about light pollution they are speaking of all the ways that man made light is changing the natural lighting of the environment. For example, all the lights of a city change the way light and dark fall. There is really no more night there, and plants or animals that are dependent on that night illumination are compromised. There are other reasons why maintaining natural light is important too.
