This week we’re sharing an episode from another Gimlet podcast called Science Vs. When a little girl, Ella Kissi-Debrah, suddenly got sick and landed in the hospital, doctors were stumped. In this episode, her mom, Rosamund, takes on the fight to find out what exactly happened to Ella. And the answer has BIG implications — for us all. We’ll hear from Rosamund Adoo-Kissi-Debrah and Professor Stephen Holgate. Check out GreenRoots to learn more about fighting for clean air. Check the air quality where you live.
