Car exhaust byproducts are disrupting moth pollination by degrading the floral scents essential for attracting these nocturnal pollinators, according to a new study published in the journal Science.
Air pollution, particularly ozone and nitrate radicals from car exhaust, impairs moths' ability to locate evening primrose flowers by altering the flowers' scent.
This reduction in pollination could significantly affect the reproduction of plants reliant on nocturnal pollinators, with broader implications for ecosystems and human food security.
Despite the challenge, reductions in these pollutants since the 1980s show potential for improvement through further environmental protections and shifts to greener energy sources.

This month UNESCO included date palm trees and related traditions on its list of the world's cultural heritage - but warming temperatures are harming production.
