Light Pollution

      Nowadays, environment issues are negative aspects of human activity on the biophysical   environment.The pollutions are getting more serious nowadays; there are few types of pollutions such as light pollution, water pollution, air pollution, noise pollution and also radioactive pollution. 

                   In most of the world’s large urban centres, stargazing is something that happens at a planetarium. But when artificial outdoor lighting becomes inefficient, annoying, and unnecessary, it is known as light pollution.  Many environmentalists, naturalists, and medical researchers consider light pollution to be one of the fastest growing and most pervasive forms of environmental pollution.




                     There are several causes of light pollution, including over illumination, sky glow, glare, clutter and light trespass.Over illumination is the use of artificial light beyond its specified purpose. The main causes of light pollution are  the street lamps and security lights found in suburban areas, and lit signs and lit commercial        buildings in urban areas. Most of the lights from these are wasted and go straight up into the sky. As we all know, the sky doesn’t need to be lit up at night.

        Bright electric lights can also affect the inhibition of birds. There are many types of birds that use to fly in the night and especially during inclement weather with low cloud cover, they normally are confused during passage by brightly lit buildings, communication towers, and other concrete structures. “Light attracts birds and disorients them,” explains Michael Mesure.



      To prevent this light pollution, as a human being we should lend a hand to help survive our only one earth. 
We can use the minimum level of illumination necessary to light a property.
         Besides that, the bulkhead or porch lights are cheaper than security lights, it use less energy, and have reduced glare. We can also try to do activities requiring a light during the day time, and use the time to sleep. 


We should take responsible to our Earth. So let's put effort on it NOW!
