"Dark Sky Compliant"
So, you ask, "What is that?" I'd never heard the term before I saw a notice asking everyone in Sanibel, Florida to modify all their outdoor lighting. In a nutshell, it means reducing light pollution while allowing the stars and moon to be more visible to people, but more importantly, the wildlife that biologically depend on it. Sea turtles nest on the beaches there. The loggerheads depend on the moonlight to lay their eggs, and the hatchlings to find their way back to their ocean home. Reducing artificial light gives them all a better chance at birth survival.
