Skyglow and especially direct streetlight pollution alter moth communities.

Summary: Have you ever noticed how bright the night sky is near a city? This extra light is called light pollution, and it is causing big problems for moths. Scientists looked at two types of light pollution: the general glow in the night sky (skyglow) and direct light from streetlamps. They found that both types reduce the total number of moths in gardens. Direct streetlights also lower the number of different moth species. This light acts like a filter, only letting moths with certain traits survive. Since moths are an important food source for other animals and help pollinate plants, losing them could harm the whole ecosystem.
