In this episode of Science Quickly, host Rachel Feltman talks with Yale University epidemiologist Colin Carlson about new research showing that the global wildlife trade is spreading dangerous pathogens far faster than scientists once thought. The conversation challenges the idea that pandemic risks are limited to distant “wet markets,” revealing how everyday wildlife trade—from pet stores to industrial farms—brings animals, people and diseases into close contact. Carlson explains why a stronger investment in basic science is critical to preventing the next COVID‑like pandemic.
