Daytime Light Pollution From Buildings May Harm Wildlife
According to a recent article in the journal Frontiers in Ecology and the Environment, artificial polarized light affects aquatic insects in particular but also waterbirds, turtles, reptiles, fish, crustaceans, and echinoderms. Reacting to light from artificial sources, birds become disoriented, and insects mate and lay eggs in inappropriate locations. Animals may fruitlessly seek to feed at parking lots full of shiny cars, and food webs can be altered when prey species are drawn in unusual concentrations to a polarized light source such as a glass curtainwall, where predators easily catch them and then themselves fall prey to other predators drawn to the easy feeding site.
The paper’s authors suggest reducing polarized light pollution by avoiding dark, shiny surfaces such as tinted glass on buildings and minimizing outdoor lighting, especially near bodies of water.
