Light pollution refers to the excessive or misdirected artificial light produced by streetlights, buildings, and vehicles. This brightening of the night sky can obscure the visibility of celestial objects, making it difficult for people to see stars and planets. It can also disrupt ecosystems, affecting wildlife behavior and natural cycles.
In addition to its environmental impact, light pollution can have negative effects on human health. Exposure to artificial light at night can interfere with sleep patterns and circadian rhythms. Efforts to reduce light pollution include using shielded lighting and promoting awareness about the importance of dark skies for both nature and human well-being.
