Abstract:

Over the last decade, the rise of light pollution has been a significant concern for environmentalists and astronomers alike, as the brightening of night skies has begun to interfere with natural ecosystems and astronomical observations. Studies show that light pollution has increased by an average of 2% per year globally, with urban areas experiencing the most significant illumination levels at night. This rise is attributed to the widespread use of energy efficient LED lighting, which is often used excessively and directed upwards, contributing to skyglow. This lecture provides a comprehensive overview of light pollution, covering its causes, impacts, and potential solutions. The lecture begins with a definition of light pollution and an overview of its different types, including skyglow, glare, and light trespass. The causes of light pollution are then examined, including the growth of urbanization, the use of artificial lighting, and the lack of awareness about its impacts. The lecture then explores the ecological, health, and societal impacts of light pollution, including its effects on wildlife, human sleep patterns, and energy consumption. Finally, the lecture considers various strategies for mitigating light pollution, including using energy-efficient lighting, responsible urban planning, and public education campaigns.

Key Points:

• Definition and types of light pollution
• Causes of light pollution, including urbanization and artificial lighting
• Ecological, health, and societal impacts of light pollution
• Strategies for mitigating light pollution, including energy-efficient lighting and responsible urban planning.
