The Insect Crisis

A devastating examination of how collapsing insect populations worldwide threaten everything from wild birds to the food on our plate.

From ants scurrying under leaf litter to bees able to fly higher than Mount Kilimanjaro, insects are everywhere. Three out of every four of our planet’s known animal species are insects. In The Insect Crisis, acclaimed journalist Oliver Milman dives into the torrent of recent evidence that suggests this kaleidoscopic group of creatures is suffering the greatest existential crisis in its remarkable 400-million-year history. What is causing the collapse of the insect world?  Why does this alarming decline pose such a threat to us? And what can be done to stem the loss of the miniature empires that hold aloft life as we know it?

With urgency and great clarity, Milman explores this hidden emergency, arguing that its consequences could even rival climate change. He joins the scientists tracking the decline of insect populations across the globe, including the soaring mountains of Mexico that host an epic, yet dwindling, migration of monarch butterflies; the verdant countryside of England that has been emptied of insect life; the gargantuan fields of U.S. agriculture that have proved a killing ground for bees; and an offbeat experiment in Denmark that shows there aren’t that many bugs splattering into your car windshield these days. These losses not only further tear at the tapestry of life on our degraded planet; they imperil everything we hold dear, from the food on our supermarket shelves to the medicines in our cabinets to the riot of nature that thrills and enlivens us. Even insects we may dread, including the hated cockroach, or the stinging wasp, play crucial ecological roles, and their decline would profoundly shape our own story.

By connecting butterfly and bee, moth and beetle from across the globe, the full scope of loss renders a portrait of a crisis that threatens to upend the workings of our collective history. Part warning, part celebration of the incredible variety of insects, The Insect Crisis is a wake-up call for us all.

Perhaps you read a news item in the last few years about collapsing insect populations. Oliver Milman has done the hard work to put such fragments in context, and the result is a book that will be a classic on the day it’s published. Our world is literally unimaginable without the insects that make it work, and so heeding the lessons in this volume is essential to our collective future.Bill McKibben, author of Oil and Honey

The Anthropocene abounds in environmental parables made real, and harrowing. Oliver Milman has delivered a gripping and especially unnerving one: what happens when the bugs go? The top of the food chain is a happy place to be only so long as there remains a food chain to stand on top of, and, as Milman deftly illustrates, in the face of die-offs too widespread to closely track, we are rushing headlong into a precarious and uncertain future. – David Wallace-Wells, author of The Uninhabitable Earth

The Insect Crisis is elegantly written, admirably nuanced, and terrifyingly important.” – Michelle Nijhuis, author of Beloved Beasts: Fighting for Life in an Age of Extinction
