Plants, animals, and microbes have led to the development of treatments for many diseases including cancer, glaucoma, malaria, inflammatory disorders, high blood pressure, and many other disorders. The staggering loss of biodiversity today affects the ability of researchers to tap natural sources for medicine and exposes people to new risks from diseases like West Nile Virus and Lyme disease. Climate change, one of the drivers of biodiversity loss, also impacts children’s health. Aaron Bernstein, M.D., M.P.H., Associate Director of the Center for Health and the Global Environment at Harvard Medical School, Physician in Medicine, Children’s Hospital Boston, and Instructor in Pediatrics, Harvard Medical School speaks with Link TV correspondent Miles Benson on the connections between biological diversity, medicine, and health.
