Light pollution

From ArticleWorld

Light pollution is the excessive use of light or the obtrusive light made by human beings. This light can result in health effects and pose a problem to astronomers. This is due mainly to its ability to obscure most stars to dwellers in city areas and to hinder astronomical observatories. This problem can also cause a waste of precious energy resources and a disruption in natural ecosystems.

There are two major areas of light pollution. These are the annoying light that intrudes on a natural light setting and the excessive light that can lead to discomfort and adverse health. Light comes from many sources but light pollution is deemed mainly a side effect of the industrialization of the world.

The problem

The forms of light considered to be major problems are those associated with annoying, wasteful and harmful use. Many do not view light pollution as a serious problem as it does not leave a trail of damage that is clearly seen. This problem is thought to be best fought by a change in the habits of the members of society. This means the use of light efficiently with a reduction in wastage. This argument is strengthened by the linkage of excessive light use to problems with vision, hypertension, headaches and many other health concerns.

Reduction of light pollution

The reduction in light pollution depends specifically on the source of the problem. There must be a reduction in sky glow, glare and many other light related issues. Some solutions are the use of light sources that meet the minimum criteria to get a specific task completed. Others include the use of timers to shut lights off automatically or the shutoff of lights manually when they are not in use. The improvement of light fixtures can also reduce light pollution as if they are directed properly there are less side effects. A change in the type of light used is also of assistance as well as the reevaluation of lighting plans in terms of efficiency.
