China's war on air pollution is causing ground pollution

The video discusses a significant reduction in fine particulate matter emissions in China, which has inadvertently led to an increase in ground-level ozone pollution. Research from Harvard and Nanjing University highlights that the decrease in particulate matter, which absorbs radicals, has resulted in more radicals available to form ozone. The study emphasizes the need for additional efforts to reduce NOx and VOC emissions to mitigate ozone pollution, particularly in urban areas like Beijing and Shanghai.
