Germany | Survey of PAs finds 75% decline in number of flying insects over last 30 years
The number of flying insects in Germany has declined more than 75 percent over the last three decades, according to a new study of survey data collected from 63 nature preserves in the country. The “dramatic decline” in insects, as the scientists described it, was likely caused by the expansion of agriculture and pesticide use, as well as possibly climate change — and is representative of what researchers are seeing in ecosystems across the globe.
“Insects make up about two-thirds of all life on Earth,” Dave Goulson, a biologist at the University of Sussex in the UK and a co-author of the new study, said in a statement. “We appear to be making vast tracts of land inhospitable to most forms of life, and are currently on course for ecological Armageddon. On current trajectory, our grandchildren will inherit a profoundly impoverished world.”
