Losing the Dark

Children across the Globe will never know a sky dark enough for the Milky Way, we are rapidly losing night’s natural darkness before realizing its worth. Less than 100 years ago, everyone could look up and see a spectacular starry night sky.

What is Light  Pollution?

Most of us are aware of pollution in the areas of air, water, and soil, but did you know that light can also be a pollutant?

The inappropriate or excessive use of artificial light – known as light pollution – can have serious environmental consequences for humans, wildlife, and our climate. Components of light pollution include:

1) Glare: intense luminosity causing visual distress

2) Skyglow-brightening of the night star over settled regions

3)Light trespassing is where light appears in areas where it isn't required or needed.

4)Clutter -bright, distracting, and unnecessary light source groupings

Light pollution is an unavoidable consequence of modern civilization. Exterior and interior illumination of homes, advertisements, industrial properties, offices, warehouses, streetlights, and illuminated sporting venues.

The World Health Organization has already classified working the night shift as a probable human carcinogen, and the American Medical Association has expressed its unanimous support for efforts at both national and state levels to reduce light pollution and reduce glare. Our bodies require darkness to manufacture the hormone melatonin, which inhibits the production of many diseases, as well as darkness to sleep. Sleep disorders have been related to diabetes, obesity, cardiovascular disease, and depression, and current evidence shows that “long light” is one of the primary causes of “short sleep.” If we work at night or just go to bed with our laptops, notebooks, and smartphones, there's no place for this much artificial light in our lives.

How can Light Pollution collapse Earth's Ecology -

The rest of the world, including nocturnal and crepuscular species of birds, insects, mammals, fish, and reptiles, relies on darkness as well. Some are well-known, such as the 400 species of birds that migrate at night in North America and the sea turtles that come ashore to lay their eggs, while others, such as the bats that save farmers billions in pest control and the moths that pollinate 80% of the world's vegetation, are less well-known. Ecological light pollution is like the night bulldozer, destroying habitat and harming habitats.  without darkness, Earth’s ecology would collapse...

Our nights are becoming brighter all over the globe. The amount of light in the sky rises by an average of around 6 percent a year the World. Based on NASA photos, computer pictures at night reveal that what was once a very dark world is now virtually covered in a blanket of light. All of this light is  Electricity lost, meaning millions wasted.  This isn't the only choice, using new lighting technology and protecting current lights, we can effectively fix the issue of light pollution. Many cities and towns are now converting to LED streetlights, offering significant possibilities for waste light management. Other communities have found that merely shutting off parts of their public lighting after midnight is efficient. Even Paris, the popular "city of light," which after 1 a.m. already switches off its monument lighting, will start forcing its malls, offices, and public buildings to switch off lights after 2 a.m. this summer.

Such decreases in light would also go further in addressing light emissions, though mainly intended to conserve electricity. But we will never truly address the problem of light pollution until we become aware of the irreplaceable value and beauty of the darkness we are losing.

Few People also claim that the night sky regained its darkness in the lockdown period dut the Outbreak of Covid - 19.

We can not stop light pollution with a snap of our finger but as our responsibility, we should make sure that lights in our home are turned off after 1 a.m and explaining this issues to others you will help bring awareness to this growing problem and inspire more people to take the necessary steps to protect our natural night sky.
