We’re exposed to plenty of invisible risks in our daily life: toxic compounds in the fabric of our couches, contaminants in the water, and pollutants in the air. A lot of the time, we don’t think too much about them. But sometimes, the invisible becomes suddenly, acutely visible. A story about the air we breathe, the risks we can live with, and what it means to become a citizen of a place. Featuring Susan Scott Peterson, Stella Peleato, Dr. Deborah Gentile, Rashmi Baliga, and Linda Wigington.
