Wgtd's The Morning Show With Greg Berg

Dr. Arturo Casadevall discusses his fascinating book "What if Fungi Win?" Dr. Casadevall has been studying fungi for more than forty years. They are extraordinary organisms - remarkably diverse - and absolutely essential for human life. They also pose a grave threat to us with fungal diseases that affect both human beings as well as our food supply. Dr. Casadevall also talks about all that we still do not understand about fungi and the ways in which research has fallen short. "I want to help change the way we practice science," he says at one point.
