We are losing 9% of insects per decade

Van Klink et al. 2020 have examined trends in insect abundance around the world and have shown that terrestrial insects are in desperate long-term decline, but that insect populations in rivers in countries with strong water pollution laws have been recovering in recent years.

This is the first study to show that, on balance, insect abundance is in steep decline worldwide – 0.92% per year which translates to an average loss of 8.81% per decade. Studies using other methods (including direct measurement) have produced insect population decline figures of between 2.2 and 2.7% per year.

If these steep declines are not addressed then there will be further damage to ecosystems and their ability to support crops and life on Earth. MORE
