The Atlantic, 2017: "In western Germany, populations of flying insects have fallen by around 80 percent in the last three decades... By analyzing the Krefeld data—1,503 traps, and 27 years of work—Hallmann and his colleagues have shown that most of the flying insects in this part of Germany are flying no more. Between 1989 and 2016, the average weight of insects that were caught between May and October fell by an astonishing 77 percent. Over the same period, the weight of insects caught in the height of summer, when these creatures should be at their buzziest, fell by 82 percent.
