Summary
Human activities are altering environmental "smellscapes" — the chemical signals that plants and animals use to communicate. Air pollution, fertilizers, fungicides, and climate change are disrupting the volatile organic compounds (VOCs) that organisms rely on for reproduction, foraging, navigation, and pollination. In Egypt, France, and Italy, changing climates are affecting aromatic crops like jasmine, tuberose, and bergamot. Scientists warn these olfactory disruptions pose serious risks to wildlife, including impaired insect reproduction, disrupted foraging behavior, and reduced crop pollination.
Key quotes
· 3 pulledA growing body of research shows how air pollution, fertilizers, and fungicides are altering the chemical signals that plants and animals use to communicate.
Scientists warn that insect reproduction, foraging, navigation, and even the pollination of crops could be affected.
In Egypt, increasing temperatures are shrinking yields of aromatic jasmine flowers; in France, extreme drought has reduced the production of fragrant, night-blooming tuberose; in Italy, climatic extremes are altering the characteristic floral, citrusy scent of bergamot.
