The Problems of Light Pollution  Light pollution: Any adverse effect of artificial light including sky glow, glare, light trespass, light clutter, decreased visibility at night, and energy waste.  Light pollution is not only a hinderance to astronomy, but it also impacts us directly. Light pollution: is a  risk factor for cancer to people is a  disturbance to animals is a  waste of energy, resources, and money is a  security risk to your property and  obscures our view Good Outdoor Lighting Should: Optimize visibility at night for what we want lit Minimize energy consumption Minimize impact on the environment and ourselves Minimize glare Minimize light trespass Effects of Light Pollution In  disrupting ecosystems , light pollution poses a serious threat in particular to nocturnal wildlife, having negative impacts on plant and animal physiology. It can confuse the migratory patterns of animals, alter competitive inte...
