It stresses us and wildlife, burns energy, and contributes to the decline of insect populations and to bird deaths at windows.
Over-illumination can make way-finding and nighttime tasks less safe. Your eyes take too long to adjust when there’s too much contrast between brightly lit and darker areas. See photo.
Research suggests that artificial light at night can negatively affect human health, increasing risks for obesity, depression, sleep disorders, diabetes, breast cancer and more.
Many animal rely on natural cycles of daylight and darkness to trigger and regulate behaviors such as hunting, hiding from predators, mating, nesting, navigating, and communicating. Bright lights confuse migratory birds, drawing them toward fatal window hazards and causing them to expend precious energy needed for migration. Resident birds also are affected: it can increase their breeding failure. Insects throng to outdoor lighting, where they are easy pickings for predators that kill and eat them at such unnaturally high levels it is impacting their overall populations.
Plants too depend on natural cycles of daylight and darkness to regulate processes such as flowering, leaf drop, and growth form.
