Cathy Le Fay, a NOAA Fisheries expert, explores how ancient DNA reveals the impact of agriculture on human health. She discusses the emergence of infectious diseases over the last 35,000 years, showing that close contact with domesticated animals heightened disease risks. Their research also highlights how analyzing whale feces sheds light on toxic algae in warming Arctic waters, demonstrating the complex interactions within marine ecosystems. The findings underscore the broader implications of climate change on both wildlife and human health.
