Controlling Wasted Spill Light Saves Energy, Environment
Which of the following is NOT affected by light pollution? (Answer below)
    A. Migratory birds
    B. Water pollution
    C. Tidal flow
    D. Automobile drivers

What is Light Pollution
Light pollution occurs when artificial light gets reflected and/or shines upward into the sky, where it is wasted instead of being contained where it is needed. You might notice that the closer you live to a city, the fewer stars you are able to see at night. Limited visibility of the stars is just one adverse effect of light pollution. Other negative effects include wasted energy and the resulting water and air pollution, damage to nocturnal wildlife and ecosystems, and reduced safety, security, and visibility at night.

Can I Have Sports Lighting and Dark Skies?
When considering a sports-lighting project, research lighting ordinances that might be in effect in your area. Also consider neighborhoods, airports, or highways that are near your facilities or could be built nearby in the future. Don't hesitate to investigate a lighting manufacturer's reputation, abilities, and past experiences in working with local authorities and private property owners regarding spill and glare issues.

Thanks to advances in the reflector system efficiencies and aiming design of some sports lighting systems, more light can be directed onto the playing surface instead of being wasted as spill and glare light. As a result, fewer fixtures are needed to purchase, install, and operate. That means less energy is necessary to achieve the same amount of light on the field. The result: darker skies, less energy consumption and cost, better environmental conservation, happier neighbors, and improved visibility at night.

Answer: C. Research has shown that light pollution does affect the timing of some birds' migration, contributes to water and air pollution, and impairs visibility of dirvers at night.
