Scientists say the night is lost due to increased use of artificial light all over the world. They found this picture after researching several photos of the night.
Scientists say the increase in the perimeter of the artificial light per year has increased by two percent between 2012 and 2016.
They fear that the loss of the night will have negative effects on humans and animals.
The study uses NASA satellite radiometer images, which can measure nighttime intensity. A report related to this has been published in a journal called Science Advance.
Studies have shown that the intensity of light decreases or leads over time and countrywide. The intensity of light in Spain and the United States, the two brightest countries in the world, is the same as before. But it is increasing in South America, Africa and Asia. But the intensity of lightning in Syria and Yemen has decreased.
The satellite image of the night reflects the world's bright sea-like and spider-like light, but it also has a harmful effect on human health and the environment.
In 2016, the American Medical Association officially highlights the harmful aspects of high-powered LED light. It is said that blue light diffraction in LEDs is high.
Recent research in another journal Nature says, artificial lighting is reducing pollination, which reduces the activities of night-westerly insects.
Christopher Kiba, the chief researcher of Geoscience at the German Research Center, said that artificial light brought about the most dramatic changes among humans, which have been influenced by nature in nature.
Kiba and his colleagues hope that artificial light decreases in rich countries like USA, UK, and Germany.
Low light more eye sight
At present, natural night sky is hard to get anywhere in Europe. Artificial light has adapted to the bright night sky. Professor Gaston said, "Human conflict with the environment always brings disaster, light pollution is also an incident, it is very difficult to fix or change."
'The light should be used wherever needed, unnecessary lighting is becoming a cause of damage. 'Says Professor Gaston.
Dr. Kiba said, even if the city is reduced to light, it will not affect our eyes, because people's eyes depend on the diversity of light and darkness, not on quantity of light.
'Large lamps used for bright lighting or decoration can be reduced, but better light will be possible in less light. '
"It will also reduce the energy waste, but national and international data say the world is in full swing.
