Some of the consequences of light pollution are immediate and obvious—for example, a moth that flies into a streetlamp may die on impact. But there are also less visible, possibly more damaging effects, such as changes to predator-prey and plant-pollinator relationships that can reverberate through ecosystems.
|1||Fatal attraction||Illuminated skyscrapers and spotlights can lure migrating birds. Animals may become disoriented and end up in deadly collisions or perish from exhaustion.|
|2||Dining by streetlight||Streetlamps, floodlights, and other luminous objects attract a wide range of insects at night. Predators home in on light-loving swarms to take advantage of the congregated prey.|
|3||Lonely nights||Nighttime lighting drives away some nocturnal pollinators, reducing the ability of plants in lit areas to bear fruit.|
|4||Shifting communities||Artificial illumination at night can increase the proportion of microorganisms in freshwater sediments that are able to photosynthesize under low light levels. |
|5||Desynchronized||Artificially lit nights can perturb an animal’s circadian rhythms, altering the timing of activities, such as sleep, foraging, mating, and migration, that are tightly controlled by the body’s internal clocks.|
