Many people have wondered why they can’t see the stars during the night regardless of the fact that there are no clouds. Nowadays, light pollution affects everyone because there is always a source of light even if we all sleep.
Based on the latest study, 80 percent of the world’s population suffers because of light pollution, meaning that eight out of ten people cannot see the Milky Way at night.
Artificial lights represent the primary source of light pollution. Unfortunately, the unusual bright sky is visible throughout the world, especially in countries such as Qatar, Kuwait, and Singapore, whereas 99 percent of the European and United States population have light-polluted skies.
According to Dr. Christopher Kyba, from the German Research Centre for Geosciences in Potsdam, many sources of artificial light contribute to this massive pollution, such as illuminated billboards, cars’ headlights and windows from businesses or homes.
Based on the latest study, called ‘The New World Atlas of Artificial Night Sky Brightness,’ artificial sky glow is caused by the luminance of the artificial night sky. Unfortunately, experts have only a little information about this phenomenon until now because further research is needed.
If there were no source of artificial light, then we would be able to see the Milky Way or at least most of the stars every night. However, artificial sky glow acts as a fog making one-third of humanity unable to see the Milky Way.
Worse, astronomers also have a hard time trying to study the stars and the Milky Way, because this fog covers most their sky view. Unfortunately, this pollution can lead to severe consequences not only on humans but also on animals and plants.
Experts established that light pollution might influence the growth of pollinating plants and affect the behavior of animals. For instance, moths depend on light so they can become confused because of the artificial light.
All in all, researchers will double their efforts in order to find a new strategy and to develop a new approach to this problem. Furthermore, officials and world’s organizations must become aware of this situation and come up with a solid initiative that will provide the next generation with the privilege of still being able to watch the stars and the Milky Way without worrying about light pollution.
