In this study, the definition, sources, components, and effects of light pollution were examined. Photographs in which the pollution caused by the light is visually evident were added to the study. In order to examine the effects of light pollution on the health of living things, studies in the literature have been meticulously scanned. It is believed that bringing together various research in this study will contribute to the world of science and will pave the way for new research by scientists. The study reveals whether there is a link between light pollution in human health and cancer types, obesity, birth health, sleep disorders, and difficulty concentrating. A separate title has been created for the effects of light pollution on animal health. In the study, research on animal species such as moths, birds, Caretta Caretta, grass mice, chicks, and ant species were included. In addition, some studies on the general effects of light pollution on all animal species are presented.
