As a pediatrician practicing in Houston, I understand all too well how much our county’s “F” grade for ozone in our air affects my young patients. I recently testified at a public hearing in Arlington held by the U.S. Environmental Protection Agency about just how dangerous this poor air quality is for children. My 10-year-old patient with asthma, Alexander, came with me. He carries his asthma inhaler in his backpack at all times and is not allowed to play outdoors on bad-air days because he is at such high risk for severe asthma flare-ups. I brought him with me to show our elected officials here in Texas the toll that air pollution takes on children like Alexander.
