Night Lights, also known as "light pollution", is the presence of artificial light in places where it wasn't normally present. This is especially concerning because it can disrupt the natural rhythms that are associated with night-time darkness. Night lights can be found in many places including street lighting, security lighting, advertising, amusement parks, residential lighting, and navigation beacons. Almost every street has some form of night lighting, and in larger cities, this adds up to a huge quantity of lights. At night, these lights create a huge amount of light in the sky which can be seen from miles away. This not only affects the environment by disrupting the light and dark natural cycle, but it also wastes energy and can cause significant amounts of light pollution. Light pollution can have a negative effect on the environment and animals. Artificial lighting can disrupt the natural cycle of light and dark and cause disruption to birds, animals, and other wildlife. Nocturnal animals rely on darkness to forage and hunt, and even subtle changes in light can cause these animals to flee or become disoriented. Artificial lighting can also mess with migration and reproductive patterns. Night Lights can also negatively affect humans as well. Some studies have demonstrated that excessive night lighting can cause health problems such as eye strain, headaches, and even fatigue. Overall, Night Lights can have a significant impact on our environment and can have negative effects for animals and humans alike. It's important that people are aware of the effects of light pollution and work to reduce its presence as much as possible.
