Light pollution is the excessive or misdirected artificial light produced by human activities. It happens when outdoor lights are not properly shielded, allowing light to scatter in unwanted directions, such as up into the sky or across properties, instead of being directed towards the intended areas. This causes a brightening of the night sky, interfering with astronomical observations, disrupting ecosystems, and affecting human health and energy efficiency.
