We bet that many of you did not know that it is International Dark Sky Week until the 12th April.
It is an annual event taking place during the week of the new moon every April.
Why is this important?
Researchers found that more than 3,300 moth species and hence more than 95% of native butterfly species belong to the group of nocturnal insects. About 50% of all insects are nocturnal, relying on darkness and natural light from the moon and stars to navigate, or to avoid predators.
Flying insects, in particular, are attracted to lamps, sky beamers and neon signs and die there through exhaustion. Light pollution is likely an important reason for the worldwide decline of insects, which are important pollinators and play a significant role in the food web.
Fireflies, for instance, have gradually reduced in number and in some places, they have completely disappeared because of bright artificial lighting at night.
Everyone can reduce light pollution! Switch houselights off, when not needed, install motion sensor lighting outside premises and on walkways, use covered bulbs that light facing downwards for streetlights and replace outdoor lights with glare with low-glare alternatives.
