Disagree that it's all about carelessness. Urban growth happens because people need places to live and work, and lighting is crucial for safety at night. Honestly, most of us are too busy with daily life to even look up at the stars, let alone worry about astrophotography. Sure, light pollution isn't great, but calling it a proof of prioritizing vanity over sustainability feels overdramatic. We have streetlights and signs for practical reasons, not just to show off. Maybe we can find better lighting solutions, but framing it as some cosmic tragedy misses the point of real world needs.
