The Bannau Brycheiniog Dark Sky Festival 2024 highlights the importance of preserving the region’s pristine dark skies, recognized as an International Dark Sky Reserve since 2013. This recognition underscores the need to combat light pollution, which not only obscures our view of the stars but also adversely affects wildlife and contributes to climate issues. The festival encourages individuals to become “Dark Sky Champions” by implementing simple changes such as turning off unnecessary lights, closing curtains, using motion detectors, and selecting environmentally-friendly lighting options. By making these small adjustments, the community can safeguard the nocturnal environment and ensure that future generations can enjoy the beauty of the night sky.
