Bees struggle to smell flowers when air pollutants combine
Key Takeaways
- Air pollutants like ozone and NOx break down flower scents.
- Pollinators such as bees and moths struggle to find food sources.
- Research reviewed 22 experimental studies on insect olfaction.
- Pollution poses a major threat to ecosystems and agriculture.
Recent research highlights how air pollution disrupts pollination by interfering with insects' sense of smell. Pollinators such as bees rely heavily on distinct floral scents to find food, but pollutants like ozone and nitrogen oxides degrade these chemical signals in the atmosphere.
Scientists emphasize that this disruption poses a significant threat to both insect populations and the broader ecosystems that depend on successful plant pollination for survival and agricultural productivity.
