Insects are disappearing, and they are leaving global food security gaps in their wake. Over the past three decades, bugs have been declining at an alarming rate across the globe — up to 1% per year, by some estimates . The drop has been so intense that some scientists have dubbed it an " insect apocalypse ." Because many insects pollinate crops, lower insect abundance has hurt everything from ecosystem health to crop yields. But historically, such consequences have been tough for scientists to measure directly. Now, in a new paper published May 6 in the journal Nature , researchers have quantified the impact of insect pollinator declines on human health for the first time. The finding was stark: Insect pollinators were responsible for an estimated 44% of the villagers' farming income and over 20% of their intake of some essential nutrients, including vitamin A, vitamin E and folate. As fewer and less-diverse pollinators visited the crops, people's income and dietary health declined.…
