"Insects Are Vanishing From the Earth -
Why Some Doctors Are Terrified"
by Dr. Joseph Varon
Excerpt: "Insects are vanishing across the globe, and their disappearance is a clear signal of environmental harm. Yet medicine and public health officials continue to treat the environment as separate from human health. When the smallest, most sensitive forms of life can no longer survive, people should pay attention.
Insects are disappearing across vast regions globally. This is not a modest decline or a simple geographic shift, but a rapid vanishing of beetles, butterflies, moths, flies, mosquitoes, bees, and entire functional groups. This phenomenon is not speculative or anecdotal; it is among the most consistently documented biological trends of the past 50 years and remains insufficiently addressed. For context, the total biomass of lost insects is comparable to the combined weight of all commercial aircraft worldwide, representing a profound ecological and economic loss.
For decades, insects were treated as background noise - annoyances at best, pests at worst. Their abundance was assumed, their resilience taken for granted. We designed agricultural systems, urban environments, chemical interventions, and technological solutions on the unspoken assumption that insects would always be there. They were too numerous to fail. This assumption has proven incorrect.
The Data Are Not Subtle: One of the most widely cited early warnings came from a long-term German entomological study that tracked flying insect biomass across protected areas over nearly three decades. The result shocked even the investigators: a decline of more than 75% in total flying insect biomass between 1989 and 2016.¹ These were not industrial zones or pesticide-saturated fields. They were nature preserves. However, many regions like Africa and large parts of Asia still lack comprehensive, long-term insect monitoring, leaving significant gaps in our understanding of global insect declines.
Subsequent studies confirmed that this was not an anomaly. A global review published in Biological Conservation concluded that approximately 40% of insect species are threatened with extinction, with declines accelerating in recent decades.² Longitudinal data from the United Kingdom, the Netherlands, Puerto Rico, North America, and East Asia tell the same story with local variation but consistent direction.³-⁶
The loss is not limited to rare or specialized species. Common insects - the ones that once filled the air - are disappearing fastest. Entomologists now openly discuss “functional extinction,” a state in which species technically still exist but no longer play their ecological roles in meaningful numbers.⁷ The significance of this issue is often underestimated.
Insects Are Not Optional: Insects occupy a central role in terrestrial and freshwater ecosystems. They pollinate plants, recycle nutrients, regulate microbial populations, control pest species, and serve as the primary food source for numerous birds, amphibians, reptiles, and fish. Rather than being peripheral, insects form the structural foundation of these systems. The loss of these foundational species could result in the disappearance of familiar foods such as coffee, chocolate, apples, and almonds, directly impacting daily nutrition.
Approximately three-quarters of global crop species rely at least partially on animal pollination, predominantly by insects. The economic value of insect pollination alone is estimated in the hundreds of billions of dollars annually. But focusing on economics understates the issue. Without insects, food systems collapse not just quantitatively, but qualitatively. Nutrient diversity declines. Resilience vanishes. Dependency on industrial inputs increases. A study published in PLoS One found that the decline in insect pollinators could lead to a reduction in the concentrations of key vitamins such as vitamin A and folate worldwide, amounting to a 40% decrease in nutrient density in certain crops. Ecological systems tend to fail abruptly rather than gradually once critical thresholds are exceeded.
The Windshield Phenomenon Was a Warning We Dismissed: Long before peer-reviewed journals quantified insect loss, ordinary people noticed something odd: windshields stayed clean. Anyone who drove regularly in the 1970s or 1980s remembers scraping insects off headlights and bumpers after short trips. That experience is now rare enough that younger generations often find it hard to believe. The so-called “windshield phenomenon” was not merely a matter of nostalgia; it represented an informal yet consistent observational indicator of declining insect abundance.¹⁰ When millions independently notice the same biological absence, the observation warrants scientific attention. Nevertheless, it was often dismissed as anecdotal, unscientific, or irrelevant.
In medical education, trainees are instructed not to disregard patient-reported symptoms solely due to challenges in quantification. In ecological science, however, similar observational evidence was often disregarded.
Mosquitoes, Misunderstood, and Essential: Few insects are more universally despised than mosquitoes. Their role as vectors of infectious disease makes them easy targets for eradication campaigns, and their decline is often celebrated. But ecosystems do not allow selective deletions without consequences. Mosquito larvae are a primary food source for fish and amphibians. Adult mosquitoes feed birds, bats, reptiles, and other insects. Their disappearance reverberates through food webs in ways that are poorly modeled and rarely discussed.¹¹
The belief that undesirable species can be selectively removed while maintaining ecosystem stability reflects a mechanistic misconception, similar to the outdated medical notion that symptom suppression equates to disease resolution. Natural systems do not benefit from simplification; rather, they are adversely affected by it."
