The world doesn’t sleep anymore—and it’s killing these night dwellers.

Humans have a weird obsession with never turning the lights off. City skylines glow through the night, porch lights burn long after everyone’s asleep, and even the stars are getting drowned out by artificial brightness. But all this light we love? It’s messing with the creatures that depend on the dark.
Nocturnal animals evolved to thrive under moonlight and shadows. Their eyes, behaviors, and instincts are all tuned for the quiet calm of the night. Now they’re facing a world that barely remembers what real darkness looks like. From tiny insects to top predators, light pollution is throwing off feeding, mating, migration—you name it. And while most of us don’t even think twice about it, they’re struggling just to make it through the night. These 14 creatures are in trouble, and it’s our 24/7 glow that’s pushing them closer to the edge.
