This guest gets us thinking about Earth Day coming up later this month. Daniel Kleinman is Professor of Sociology at Boston University, but was a senior dean of the Graduate School at the University of Wisconsin-Madison when he co-authored "Vanishing Bees: Science, Politics, and Honeybee Health". Whether or not we know the importance of bees in our ecosystem and some of the stresses critically affecting them, we will get to expand our awareness and possibly be enlisted in some kind of activity to protect and improve the health of our bees, and through them, our own life and health.
