The Surprising Impact of Trees on Air Pollution: Should We Cut Down Oak Trees?

A new study explores the complex relationship between oak trees and air pollution. As the Earth warms, oaks emit more isoprene, a compound that can degrade air quality but also benefits clean air and enhances plant resilience. Researchers suggest controlling nitrogen oxide pollution rather than cutting down oak trees. Isoprene interacts with nitrogen oxide compounds found in air pollution, creating unhealthy byproducts. The study aims to understand the biomolecular processes plants use to make isoprene and how they are affected by climate change. The research found that increasing temperatures have a greater impact on isoprene production than increasing carbon dioxide levels. The findings can help anticipate future isoprene emissions and inform better choices for managing air pollution.
