The increased and widespread use of artificial light at night is non but impairing our view of the universe, it is adversely affecting our surroundings, our safety, our energy consumption and our health.

What is Calorie-free Pollution?

Nearly of united states are familiar with air, water, and state pollution, but did you know that calorie-free can likewise be a pollutant?

The inappropriate or excessive use of artificial low-cal – known as light pollution – can have serious environmental consequences for humans, wildlife, and our climate. Components of light pollution include:

• Glare – excessive effulgence that causes visual discomfort
• Skyglow – brightening of the dark sky over inhabited areas
• Light trespass – light falling where it is non intended or needed
• Ataxia – bright, disruptive and excessive groupings of low-cal sources

The infographic above illustrates the unlike components of light pollution and what "good" lighting looks like. (Image by Anezka Gocova, in "The Night Issue", Alternatives Journal 39:5 (2013). Click to overstate.

Light pollution is a side consequence of industrial civilization. Its sources include building outside 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 existence wasted by spilling it into the sky, rather than focusing information technology on to the actual objects and areas that people desire illuminated.
