Night Lights, also known as light pollution, has become a widespread problem across the world. It is the excessive and inappropriate use of artificial light that has negative effects on our environment and our health. Light pollution is most commonly found in highly urbanized areas. The combination of street lights, office buildings, commercial centers, and residential areas creates an increase in artificial lighting. This interferes with the natural light our planet needs to go through its daily cycle of day and night, as well as contaminates the natural night sky. It disrupts animal behaviour and creates environmental problems, such as the accumulation of greenhouse gases. Humans are also negatively affected by light pollution. High levels of exposure to artificial light can lead to sleeping disorders, eye strain, depression, and other health issues. Fortunately, many cities around the world are taking steps to address this problem. By reducing and better controlling the amount of artificial light in highly urbanized areas, cities have been able to reduce the impacts of light pollution and create a better environment for both humans and animals. The use of energy efficient lighting and increased focus on small- scale outdoor lighting has also been effective in reducing light pollution. Light pollution has become an ever increasing problem, but it is encouraging to see that cities and communities around the world are taking steps to reduce its impact. By being more conscious of our nighttime lighting, everyone can contribute to a healthier environment and a better quality of life.
