The Ecological and Physiological Case for Urban Dark Sky Policies and Implementation
A. The proliferation of artificial light at night (ALAN) is a defining, yet often overlooked, feature of the modern industrialised world. This pervasive illumination, while synonymous with progress and safety, has cast a long shadow over the natural world and human physiology. In response, a growing global movement advocates for 'dark sky policies'—regulations designed not to plunge our cities into darkness, but to manage light more intelligently and sustainably. These policies aim to mitigate light pollution by promoting responsible lighting practices, such as shielding light fixtures to direct light downwards, using timers or motion sensors, and choosing warmer-hued bulbs. The implications of such measures extend far beyond preserving starry nights for astronomers, touching upon the fundamental health of ecosystems and human populations alike. B. The ecological toll of unchecked artifi...
