Contemporary Science 6/07/11: Sustaining Life: Biodiversity & Health

Aaron Bernstein, MD, MPH,Harvard Medical School and Harvard Center for Health and the Global Environment. The loss of biological diversity is on par with the last great extinction event of 65 million years ago when roughly half of all species were lost. This rapid loss directly affects human health and well-being on a global scale. Dr. Bernstein explains the relationship between emerging disease patterns and declining biodiversity.
