John Otis, an NPR reporter, interviews marine biologist Elvira Álvarado, the 'mother of coral,' who is passionately working on coral IVF techniques to restore Colombia's reefs. She shares her inspiring journey from diving enthusiast to pioneer in marine science, while explaining the threats to coral reefs and her goals for resilience. The conversation then shifts to China, where ride-hailing drivers are penalized for smelly cars, highlighting the challenges they face and the subjective nature of odor ratings in the industry.
