Light Pollution

INTRODUCTION:-

What is Light Pollution:-

Due to all kinds of  man-made sources of light, which is the unwanted or highly luminous artificial light is the cause of the  light pollution

Like noise pollution, Light pollution is also a form of waste energy that can cause adverse or hazardous effects as well as deteriorate the quality of the environment.

Furthermore, the light that we usually see as electricity is produced by the combustion of fossil fuels, It can be said that there is a connection between light pollution and air pollution which is emitted from fossil-fuel combustion power plants. 

Therefore, control of light pollution will help in the preservation of both fuel and money, and reduce air pollution as well as more immediate problems caused by excessive light.

Although light pollution may not affect public health and welfare as water pollution and air pollution affect public health and welfare, it is an environmental quality issue.

Light pollution mostly affects professional and amateur astronomers, but also affects as well as casual observers of the night sky, as it severely reduces the visibility of stars and other astronomical events and objects.

What is Skyglow:-

The decrease in night sky visibility is the result of "skyglow", a poorly designed or directed lamp and upward-directed light emanating from the safety floodlight. This pointless light is scattered and reflected by solid or liquid particles in the atmosphere and then returned to people's eyes on the ground, reiterating their view of the night sky. The effect of skyglow from a city or city is not necessarily localized; It can be seen far away from the main source.

Affect of  Light Pollution:-

1.- With humans:-
 
Light pollution is not only a problem for astronomers and those who only want to enjoy the beauty of a starving night. Glare from street lamps, commercial safety lights and signs or even from a neighbour's bright and misplaced yard light can cause discomfort and distraction and adversely affect the quality of life of many people. 
 

2.-With animals:-

 
Light pollution also adversely affects birds and other animals. Many migratory birds, for example, fly at night, when light from stars and the moon helps them navigate. These birds are affected by the glare of artificial light as they fly in urban and suburban areas.

It has been estimated by the American Bird Conservatory that more than four million migratory birds are destroyed each year in the United States by colliding with brightly lit towers and buildings.

Light pollution is considered one of the factors contributing to the dramatic decline of some migratory songbird populations over the past several decades.

   

Causes of Light Pollution:-

the main cause of light pollution is the following.                                                                                                                                                                                                                                                                 

• the major cause of light pollution is anything which can produce light can cause light pollution.                                                                                                                                                                                                  
• The light coming out of our houses at night.                                                                                                                                                                                                  
• Large city areas with skyscrapers that emit a large amount of light.                                                                                                                                                                                                  
• Cars, bikes, buses, and trucks particularly the headlights. Busy roads in the city's at night create a lot of light, which can cause light pollution                                                                                                                                                                                                   
• Street lights: Those which are without proper covering cause lots of unnecessary light to the sky, which is the reason of skyglow and light pollution

The list never-ending, but as you can see, even the most simple things cause light pollution. 

 

 

 

LIGHT POLLUTION SOLUTIONS:-

Homeowners, city managers, and other people responsible for infrastructure can help curb light pollution, reduce energy consumption, and protect human and animal health using these recommendations from the International Dark-Sky Association and other experts. 

 

•  Use lower temperature LEDs and compact fluorescents.                                   

•  Use outdoor lighting fixtures that shield the light source to minimize glare and light trespass.                                  

•  Use dimmers, motion sensors, or timers on outdoor lighting.                                                                                                 

• Turn off unnecessary indoor lighting, particularly in empty buildings at night.                                                                                                                                                                                                  

• If you live in a high-rise building, use drapes or blackout curtains to reduce bird collisions.                                                                                                                                                                                        

• Turn off devices an hour before bedtime. When available, use apps that filter out blue wavelengths emitted by your handheld electronics.                                                                                             

• Maintain as much overnight as dark as possible. Leave the bathroom lights off if you must get up, or use a dim red light that will not disrupt your nighttime physiology.

 

 these are some of the basic solution of light pollution.

 after applying these solution in our daley lifestyle reduse the light pollution.
