Category: Light Pollution
Light pollution is the excessive or misdirected artificial light produced by human activities, which brightens the night sky and disrupts natural cycles. It impacts ecosystems, wildlife behavior, human health, and our ability to see the stars. Common sources include streetlights, outdoor lighting, and illuminated buildings, which create glare, skyglow, and light trespass, affecting both the environment and biodiversity.
