A 2017 German study found an alarming reduction in flying insect populations, attributing it partially to changes of climate and habitat. More recently, scientists from the Leibniz-Institute of Freshwater Ecology and Inland Fisheries have discovered that regions that have experienced a sharp decline in flying insects also have high levels of light pollution.
