Insects, bugs, creepy-crawlies – these small animals are often considered a nuisance (or worse) by humanity, bringing up an ongoing desire to kill or mitigate these “pests” that plague our backyards, homes, and gardens. But we’re beginning to see that, despite our cultural misconceptions, insects are actually at the foundation of our biosphere, food supply, and nearly every life process on Earth. This makes recent reports of rapidly declining insect populations all the more troubling – but can we recognize the vital importance of insects and reverse the harm we’ve done before it’s too late?
On this episode, Nate is joined by environmental journalist, Oliver Milman, to discuss the alarming decline in insect populations in the past few decades and the far-reaching consequences this has for ecosystem stability, human well-being, and the overall health of the biosphere. From pollination and nutrient cycles to being the base of food webs for countless other animals, the loss of insects has cascading effects beyond what we could imagine. Oliver outlines the human activity that is driving the worst of these trends, including how accelerating global heating is amplifying these ecological pressures.
How would a major collapse of insect populations immediately disrupt our everyday lives — and are we already starting to see those impacts? How do various sectors of human activity, from industrial agriculture to urban development, influence insect health? And ultimately, would supporting thriving insect populations require us to fundamentally rethink our relationship with the creatures with which we share the biosphere?
