Urban sky glow , which is destroying mankind's view of the universe. There are solutions to all these problems. Quality lighting is the key. Awareness of the problem and of the solutions is needed, of course, and is grossly lacking, even among lighting professionals. Lack of awareness is the problem, rather than resistance, in implementing these solutions.
Education is the key to success.
Urban sky glow will have blotted out the dark sky, just as a lighted room blots out the view of a slide show. Insist on quality lighting. Use it yourself. Such quality lighting is directed downward where it is needed, not up or sideways where it is wasted and causes glare, light trespass, and bright skies. IDA produces a regular newsletter as well as information sheets which discuss details of the issues, including effective and efficient security lighting, energy savings, and many other topics.
