In the first study of its kind, researchers have found that improved air quality in southern California had a direct effect on children’s respiratory health. The findings point to the effectiveness of smart public health policy — in other words, even as southern California experienced increases in traffic and commerce, aggressive air pollution policies resulted in cleaner air and healthier kids.
