There is a famous quote by Havelock Ellis, The Dance of Life, 1923“The sun, the moon and the stars would have disappeared long ago . . . had they happened to be within the reach of predatory human hands.” From the beginning of civilization humans have attempted to capture and control the light or fire as a source of energy. Let is be in the form of stones or coal. This attempt has definitely changed the course of civilization in both positive and negative ways.

Light pollution is a newly coined term of modern society which speaks about unwanted lighting environment thus affecting various lifeforms. The inappropriate or excessive use of artificial light – known as light pollution – can have serious environmental consequences for humans, wildlife, and our climate. Components of light pollution include:

Glare – excessive brightness that causes visual discomfort

Skyglow – brightening of the night sky over inhabited areas

Light trespass – light falling where it is not intended or needed

Clutter – bright, confusing and excessive groupings of light sources

Light pollution is a side effect of industrial civilization. Its sources include building exterior and interior lighting, advertising, commercial properties, offices, factories, streetlights, and illuminated sporting venues.The fact is that much outdoor lighting used at night is inefficient, overly bright, poorly targeted, improperly shielded, and, in many cases, completely unnecessary. This light, and the electricity used to create it, is being wasted by spilling it into the sky, rather than focusing it on to the actual objects and areas that people want illuminated.
