A few more years. Stop looking at the night sky. This doesn't just happen in our country. Rather, it will be all over the world. The reason is the light that illuminates our homes, offices and streets. The night sky is hazy because the amount and consistency of artificial light has increased significantly.
In a few years the night sky will disappear from our sight. Between 2011 and 2022, the brightness of the night sky has decreased by 7-10%. In other words, the artificial light that illuminates the ground blurs the sky. This disclosure came to light through research conducted around the world. The night sky is slowly losing its beauty. The reason is light pollution. In the process of enlightening the whole world we lose our own heaven. Due to the increasing amount of light pollution on Earth, the reflection of light between our eyes and the atmosphere is very high. This is why the sky looks blurry. I can't see the stars. Fewer stars can be seen in the sky.
Currently, only the night sky is clearly visible in hilly areas with low air pollution. Otherwise, it will be difficult to see the stars. (photograph: Reuters)
North America, Europe, Asia, Africa and South America were selected to study this issue. We asked 29,000 people in 19,000 locations around the world if they could see the night sky clearly. How much has changed in the last 10 years? So citizen scientists around the world submitted their answers. This light pollution report was then produced. Over the past decade, light pollution on Earth is said to have increased significantly. This reduced the transparency of the night sky by 7-10%.
Where there is less pollution, more stars are visible.
If you go to a place with less pollution, you can see many stars in the sky. However, it decreases as soon as you enter the city. In fact, they are no less. Air pollution and light pollution make it difficult to see. Due to artificial light, there is so much light reflection happening across the globe that it is not surprising that the stars in the sky are blurry or invisible.

Dangerous to humans and animals
Physicist Christopher Kieber of the GFZ German Research Center for Earth Sciences said the study was important for two reasons. . Second, night-light reduction regulations are being neglected around the world. In the name of development, more and more artificial light is endangering the natural landscape.
Visibility is declining by 2% each year
According to Keeba, a lot of research has been done over the past decade on the environmental impact of increased artificial light. There are rules for this all over the world. Since the amount of light in the atmosphere is debated,
deteriorating animal life cycle
Light pollution does not only affect the sky and darkness. It also affects humans and animals. Because of these, the species of fireflies is getting extinct. The way animals communicate is changing. Also their nocturnal life cycle is disturbed. Now scientists say that the only way to reduce light pollution is to improve the direction, quantity and type of lighting devices.
