Humans evolved with the rhythms of the natural light-dark cycle of day and night. Street lighting has been blamed for up to 50% of the urban sky glow due to 95% of the light directed down toward the pavement being reflected upward at reflectance rates ranging from 6% for asphalt to 25% for concrete (Ref 1). 12.

That’s enough energy to meet New York City’s total electricity needs for 2 years. Light pollution or luminous pollution can have adverse consequences on the health and quality of life for human beings. Light pollution is harming our environment, wildlife habitats, and our quality of life. Birds that navigate by moonlight and starlight can wander off course. Light pollution disrupts this rhythm and consequently there are many health effects of light pollution such as sleep disorders, increased anxiety, headaches and fatigue.
