Light Pollution Beyond the Visible: Insights from People’s Perspectives

Abstract

Light pollution, most visible in large cities through the absence of star-filled night skies, has become a growing issue of concern across many disciplines. It is not just an esthetic or astronomical problem, but a complex phenomenon with widespread effects on various sectors. The scientific literature highlights several key areas impacted either directly or indirectly by light pollution: astronomy, ecology and biodiversity, the environment and climate change, human health and well-being, the ongoing energy crisis, economy, tourism, public safety and security, and finally politics. A survey was conducted to explore two main objectives. The first was to evaluate public awareness of light pollution, particularly how individuals perceive its impact across different societal sectors. The second objective was to consult lighting experts to obtain detailed insights into how severely each sector is affected by light pollution. The data collected from both the general public and lighting experts were analyzed and compared to provide a clearer picture of light pollution’s actual consequences. This dual-perspective approach aims to identify potential gaps between public perception and expert knowledge. Understanding these gaps is essential for shaping effective awareness campaigns and informing policy decisions. Ultimately, this research serves as a foundational step toward prioritizing mitigation strategies. By aligning scientific data with social understanding, stakeholders can develop targeted interventions that reduce light pollution’s negative effects while promoting sustainable lighting practices for the future.
