It creates an ever-increasing threat to wildlife. Light pollution has increased so much from residences, public infrastructure, and industrial activity, that 80% of the world population live under skyglow and nearly every European cannot experience a natural night sky.
Invertebrates can be especially affected by ALAN, including their feeding, migration and dispersal, predator avoidance and reproduction. These impacts can potentially have sustained consequences on insect diversity and the ecosystem services that they provide. Globally 64% of invertebrates live partially or wholly at night, and they face a particularly great threat from light pollution.
Lighting is needed in many instances for road and pedestrian safety, but excessive light pollution can, and should, be reduced. National light pollution metrics and targets are the key to changing direction.
