From bats and badgers to moths, owls and amphibians, much of the natural world comes alive after sunset – yet artificial lighting is increasingly disrupting these vital nighttime rhythms. Many animals and insects depend on darkness to feed, navigate, pollinate, hunt and rest, so light pollution can disturb migration, feeding and breeding patterns across whole ecosystems.
Bright lights on trees, rivers and gardens can also disorient insects and reduce pollination, with wider knock-on effects for nature. Simple changes – like only using outdoor lighting where needed, choosing warmer bulbs, shielding lights downward, or drawing curtains and blinds at night – can help protect the nocturnal world and bring back darker skies for wildlife and people alike.
Light pollution is one kind of pollution we can actually see, making it easier to do something about. Switching lights off when they’re not needed – and keeping indoor light contained by curtains or blinds – can make a real difference for creatures of the night.
