Study: Trees may worsen Southeastern pollution

External News Details

Ronald Reagan once sloughed off the need for tougher clean-air rules, blaming vegetation for pollution. That simplistic notion was rebuffed by scientists who noted that trees help make overall air quality better by taking up pollution and they also help to cool off urban areas, which also can translate into less pollution. So the U.S. Environmental Protection Agency recommends trees for cities dealing with the kind of pollution that's challenged Louisville for decades, including this summer.

But trees do emit a chemical that can add to ground-level ozone. And a new study from Georgia Institute of Technology suggests that climate change could exacerbate that and extend the ozone season across the American Southeast.
