In this Episode, Todd speaks with Agriculturist Dr. John Ikerd. John has become a leading figure in the sustainability revolution - one who is capable of deep insights but also has the capacity to engage everyone in the conversation and work.  He has found himself at the edge of what is possible in the discipline and has turned his efforts to using his voice and position to advocate for radical change and to help others to both understand this necessity and to be able to advocate for themselves.
