Artificial Light or Electricity, a New Source of Environment Pollution

Monday, 30 July 2012

Excessive use of artificial light or electricity is a new polluting source that can affect humans’ health and environment.

Starry nights that our ancestors enjoyed will disappear from our view in the course of time.

Excessive use of artificial light like electricity in most regions of the world turned to another pollution source.

This light covers stars’ landscape at night, affects astronomy telescopes, harms human health and damages ecosystem of earth.

According to Yan Chiny, many children in the world are growing older while they never experience the scenery of primary milky galaxies in the sky. There are millions, even billions of stars in these galaxies; sun and solar system planets are also part of it. He believes that if no one can see such a sight of stars, this means that there will be fewer astronomer scholars, and the world will be deprived of having the poets whose works are inspired by these stars.

Of course, only being deprived of starry nights’ sight cannot reflect disadvantages of using too much artificial light, but also affects the efforts of scientists to find the key to the mysteries of the universe. According to one of the scientists, by not seeing the big wide world, men portray themselves great.

Humans have used only torch to light at night for centuries. Afterwards in 18th century there was oil lamps created. Finally, in 20th century everywhere was lit by electricity light. This light is now that much which it is difficult to feel the darkness anymore. The most important thing is that valuable energy resources of earth are turned into electrical energy and again this energy to some extent is wasted.

According to Chiny, the roads’ lights must only light the streets, while other non-human beings are affected. For example, migratory birds find their way based on positions of stars and migrate from North to South, but by increase of artificial light they lose their way. In cities with high brightness a large numbers of birds die by being hit on glasses of windows.

Scientists say that the artificial light also affects human characteristics associated with day and night.

Richard Stevens, an infectious disease doctor says that more cases of breast cancer have been seen with women who work for many hours under artificial electricity light in industrial countries of the world. World Health Organization has also confirmed this.

Fortunately now the lamp factories are trying to mimic the natural light, and efforts also have started to prevent light pollution as possible.
