For millennia, humanity has looked up in awe at the night sky, finding in its silent beauty a profound source of inspiration. This celestial canvas has fuelled our greatest achievements in poetry, philosophy, religion, and astronomy. Today, this shared heritage is under threat from the pervasive glow of light pollution.
This presentation will first quantify the consequences of this loss, from wasted energy and damaged ecosystems to compromised human health. But beyond these tangible effects lies a deeper, intangible crisis: a cultural severance from a universe that has always guided us.
We will argue that reclaiming the night is essential to preserving our collective story. Finally, we will translate concern into action, offering a pragmatic suite of strategies to restore the stars and ensure this ancient wellspring of wonder endures for generations to come.
