Yes, it exists.
LIGHT POLLUTION
=================
Light pollution refers to the excessive and obtrusive form of artificial light. This can include sky glow and glare that is brought about by the scattering of light in the atmosphere by minute particles of dust or water.
Cause:
Light pollution results from outdoor lights aimed upward or sideways --- the light scatters in the atmosphere and reflects back to the ground. The result is sky glow. Particles in the atmosphere responsible for air pollution accentuate light pollution by increasing the amount of light scatter. According to the International Dark-Sky Association, light sources that emit blue light are particularly disruptive to night skies due to greater light scattering.
Effects:
According to the National Park Service, city lights as far as 200 miles away diminish views of night skies. Light pollution is a major concern for observatories as lights from urban areas compete with lights from stars and planets, reducing visibility of the objects that observatories study. This type of pollution also affects wildlife and plants. Night lights disorient hatching sea turtles, migrating birds and nocturnal animals. Lights attract insects, which may in turn interfere with pollination of nocturnal flowers. In humans, light pollution can interfere with natural circadian rhythms by preventing the production of melatonin, the chemical that regulates sleep patterns. Low melatonin levels have been linked to increased cancer risks.

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