We expect light. Without light, there would be no civilization. This fauna would not have been born. That is why we call the sun that pierces the chest of darkness the 'Lord of the World'. How much talk about light, how many adjectives! Literature and songs have been written about him. However, when that light becomes the cause of pollution, it seems to be a problem. Yes, the dictionary of pollution includes 'light pollution' or 'light pollution'. Almost the whole world is being polluted by this pollution. Our district East Burdwan is no exception. From the light of the lighthouse outside the house to the intense halogen light, the colorful neon light is making the night dark. In fact, we do not understand the importance of darkness. In addition to light, the fact that darkness is also essential for this ecosystem probably does not occur to us.

In fact, it started from the time I learned to light that fire. Learning to light a fire is one of the most important events in the history of human civilization. That fire carried the people forward, but, in that night light, the wild animals, the birds got into trouble. That light a few million years ago has now multiplied many times over. Wild people have been civilized. Therefore, the interests of business and self-promotion have become bigger than their own survival. From cities, small towns to villages পর artificial light is burning from sunset to sunrise. And in the developed countries of the world, this light is many times more. A study by a university in Italy found that two-thirds of the world's people do not understand the light of nature at night. The reason is the abundance of artificial light.

Experts have categorized light pollution into several categories — light trespass, over-illumination, light clutter, and so on.

When a bright light on the side causes discomfort to others, it is called 'light trespass'. For example, when a light on the street or outside enters the house through the glass window of another's house, it is called 'light tracepass'. ‘Over-illumination’ pollution causes light pollution over a wide area in very bright light. In the case of ‘light clutter’ pollution, a huge variety of colored lights confuse and mislead people. An example of this can be seen in the city of Las Vegas, USA. But it is good to know that the night sky is not completely black. This space is full of cosmic soft light. According to scientists, the night sky is about 40 times brighter and brighter during the full moon than the new moon.Artificial satellite images are usually analyzed and measured and measured with the help of other mathematical formulas. As of 2012-13, the sky in Hong Kong was the brightest. Singapore took this place in 2016. A few years ago in Paris a few years ago, almost all the lights in the city were turned off for a while in order to reduce the use of conventional energy that was rapidly running out and to get some return to the fog of the night. Some cities in India also participated in this work in Paris. Dear Burdwan was not left out either. In this way, if self-awareness is increased, light pollution will come under control.

Animals, including humans, have a 'biological clock'. With the help of which animals can understand the difference between day and night. As a result of light pollution, it has started to deteriorate. Sleep is disrupted. This insomnia has an effect on diet and reproduction. As a result, scientists fear the extinction of various animals in the near future. What happens to humans? Experts say that when the sun's light goes out, the hormone called 'melatonin' in the blood increases in the human body in the dark. Which is responsible for our sleep. Beta endorphins are released during sleep which act as a normal pain killer. Proper sleep determines the amount of insulin in the body. But as a result of light pollution, diseases like insomnia, diabetes and heart disease are on the rise. According to The New York Academy of Sciences, light pollution also indirectly causes diseases such as cancer.

The International Dark Sky Association was formed in 1986 to control light pollution. They are still carrying out various awareness programs. America also has anti-light pollution laws. This law imposes various restrictions on the use of unwanted lighting. There is also a system of punishment if necessary. The National Park Service's Natural Sound and Night Skies Division is also exploring the skies of various national parks and sanctuaries.Extremely bright LED light is associated with magical neon lighting. There are lights in various parks and gardens. But the problem is that sometimes the lights in all those places are not turned off on time. And all this light is having an effect on animals, especially birds. Such is the claim of scientists. Large lights are lit in the coastal areas of Damodar throughout the night to extract sand. Environmentalists claim that this is affecting the ecosystem in the areas adjacent to Damodar. So it is very important to be aware of controlling the use of light.
