Dear Green Mama: My family and I live in North Florida. My son has asthma and allergies and he is attending public school in the fourth grade. His teacher refuses to remove her plug in air fresheners. I sent a note to this teacher and a note from his doctor explaining my son's asthma and offered to buy something less offending to his health. She responded saying she has been a teacher for 28 years and never had a problem, she will not teach in a musty room and did not feel complete without perfume.
