“Ozone forms when volatile organic compounds (VOCs) released by some vegetation, vehicles and chemical industries react with nitrogen oxides (NOx), which are emitted mostly by traffic and industry.”
So how about getting rid traffic and industry instead of getting rid of trees??

"Trees make air quality bad" is the most incredible take I expect to read all week.
@silvermoon82 @IcooIey “They found that vegetation accounted for about 10% of the total VOC emissions in Beijing between May and July 2021, the study period, and that human activities, such as vehicle emissions and industrial chemicals, accounted for the rest.”
This is scientifically interesting, but the framing that the trees are making the problem worse…
@c0dec0dec0de @silvermoon82 it’s maddening!
@silvermoon82 I’m not arguing with the science, that’s factual, that some tree species release VOC that can lead to increase in ground level ozone when combined with NOx. But the framing sure makes it look like “trees make air quality bad” instead of the far more nuanced message that some trees + TRAFFIC make AQ bad. And solutions could range from have a greater diversity of urban trees to reducing auto emissions or limiting vehicles. Headline should be Traffic bad for urban AQ!
