What Is Light Pollution??? 

The Components of Light Pollution
1) Urban Sky Glow This is what you see when you look at a city from a distance, a dome of light covering a large area of the sky and blocking your view of the stars. Proof that you don't have to live in the city to effected by it wasteful lighting.
2) Light Trespass The light from a neighbor, business, roadway, billboard etc. shining onto your property without your consent. This is similar to someone playing their stereo loudly late at night keeping you awake.
3) Visual Clutter Simply put, too much light. This can make it difficult to find your way around at night, Confusing to both visitors as well as the elderly, not a nice welcome mat.
4) Glare This is when light shines directly into your eyes, like an oncoming car with high beams. Glare often makes it difficult to see the traffic lights, roadway & lane boundaries and even pedestrians. There is nothing good to said about glare, it is most often the result of poorly aimed lighting. Remember if you can see the light bulb, it is probably causing glare.
5) Energy Waste Light shining outward and upward into the sky is wasted. This waste is estimated at costing over One Billion Dollars a year in the United States alone, with recent figures reaching as high as Two Billion Dollars. This is a lot of money to see the bottoms of clouds, birds, and airplanes.
