Light pollution of the environment. Space monitoring of this problem.
Light pollution (otherwise known as backlighting) is the illumination of the night sky by artificial light sources, the light of which is scattered in the lower atmosphere, interfering with astronomical observations and changing the biorhythms of living beings, leading to the death of some of them. This phenomenon is sometimes also referred to as light smog.
