Light pollution, often overlooked, disrupts ecosystems, wildlife, human health, and energy efficiency while diminishing the beauty of the night sky. Its components - glare, sky glow, light trespass, and clutter - result from excessive and poorly directed artificial lighting. Addressing light pollution is vital as most urban and suburban areas are heavily affected. Fortunately, it is reversible. Solutions include adopting "Dark Sky" lighting, which focuses light downward and uses warmer Correlated Color Temperatures (CCTs) of 3000K or less to reduce blue light pollution and its harmful impacts on flora, fauna, and night sky visibility.

While warmer CCTs slightly increase energy costs, they support ecological health and improve the ambiance of outdoor spaces. Dark Sky certification, provided by DarkSky International, ensures lighting meets strict standards. Success stories like Presteigne and Norton (1st Dark Sky community in Wales & mainland England) demonstrates how communities can balance environmental stewardship with responsible lighting practices.
