Although many studies have documented how artificial light harms individual species, the impacts on whole ecosystems and the services they provide, such as crop pollination, is less clear. Although changes to natural light conditions… Changing light conditions due to human activities represents an important emerging environmental concern. For example, exposure to artificial light at night can reduce food availability and enhance predation control by ladybeetle, a known visual predator, reducing the …

White LEDs have a relatively wide range of wavelengths, but also have significant peaks in the blue and green lights, to which many biological processes are sensitive. The effect of artificial light on pollinating and seed dispersing species could result in reduced or enhanced recruitment among plants leading to changes in vegetation composition (figure 1 c) , but with few exceptions the effects of artificial lights on these ecosystem services has not been studied. Experiments showed that artificial light at night can have bottom-up effects on aphids, mediated by plants these insects depend on for food, but also top-down effects mediated by their predators (e.g.
Alterations in foraging behavior may … Artificial light is composed of visible light as well as some ultraviolet (UV) and infrared (IR) radiations, and there is a concern that the emission levels of some lamps could be harmful for the skin and the eyes.

Health Effects of Artificial Light 4 ABSTRACT A: Potential health impacts on the general public caused by artificial light In general, the probability is low that artificial lighting for visibility purposes induces acute pathologic conditions, since expected exposure levels are much lower than those at

ladybugs or slugs) or parasites. Early artificial lights (such as low-pressure sodium light) often have a much narrower range of wavelengths than moonlight, and thus can significantly affect the visual perception.
The ultraviolet and the blue components of light have … Both natural and artificial light can also disrupt the human body clock and the hormonal system, and this can cause health problems.
