More Than 40 Percent of World’s Insect Species on Fast-track to Extinction
PORTLAND, Ore.— Authors of a major new scientific review of the catastrophic decline of insects say a “serious reduction in pesticide usage” is key to preventing the extinction of up to 41 percent of the world’s insects within the “next few” decades.
The review, published online this week in Biological Conservation, highlights that reversing the insect declines will require an “urgent” push to replace the ever-escalating use of harmful synthetic pesticides and fertilizers with more ecologically based, sustainable farming practices.
“This analysis is an alarming wake-up call that we need to dramatically reduce pesticide use,” said Tara Cornelisse, an entomologist and senior scientist at the Center for Biological Diversity. “Dumping more and more insecticides on our food crops is like fixing a noise under the hood by yanking out the car’s engine. Insects are the foundation of every healthy ecosystem, so we need to quit poisoning landscapes with millions of pounds of toxic pesticides every year.”
Among the authors’ most sweeping conclusions is that “A rethinking of current agricultural practices, in particular a serious reduction in pesticide usage and its substitution with more sustainable, ecologically-based practices, is urgently needed to slow or reverse current trends, allow the recovery of declining insect populations and safeguard the vital ecosystem services they provide.”
The meta-analysis of 73 studies assessing insect declines over a period of at least 10 years found that industrial farming practices driving habitat loss and extensive use of pesticides and fertilizers is associated with 47 percent of reported declines.
