Humans Are Changing How Nature Smells, With Risks for Wildlife
Human activities—from air pollution to fertilizers and fungicides—are reshaping the planet’s “smellscapes,” degrading the volatile organic compounds that many species rely on for communication. Laboratory and field studies show that ozone and nitrogen oxides break down floral scents, cutting bee scent recognition by up to 70% and shrinking moth detection ranges to a quarter of pre‑industrial distances. These chemical disruptions impair pollination, mating and nutrient‑recycling behaviors essential to ecosystem health. Researchers warn that continued olfactory pollution could exacerbate insect declines and threaten the pollination services that support roughly 70% of global food production.
