LIGHT POLLUTION: NEED OF THE HOUR

Abstract

Light pollution the excessive or misdirected artificial light at night — has become a critical environmental issue with significant consequences for human health, ecosystems, energy consumption, and astronomical research. Despite its ubiquity, light pollution remains underrecognized in environmental policy frameworks, particularly in developing contexts. This study synthesizes existing research, analyzes empirical evidence, and examines the multifaceted effects of artificial light at night (ALAN). Results show that light pollution disrupts circadian rhythms, alters animal behavior, reduces ecological service values, and obscures night skies. The findings highlight the urgent need for policy interventions, technological innovations, and public awareness campaigns to manage and mitigate light pollution effectively. The study concludes that responsible lighting practices are essential for sustainable urban development and environmental protection.
