Since grade school, most of us have been taught germ theory so consistently that we may have forgotten that it is a theory in the first place. Today, Marcy Cravat, the producer of the documentary "Terrain" challenges our presumptions. She contrasts germ theory with natural law (or what some call terrain theory). And she explains how these drastically different approaches shape our understanding of the world and our own health.

Marcy differentiates between the two - exploring a number of related subjects including contagion and resonance, and the pleomorphic cycle of healing. Along the way, she celebrates the intrinsic wisdom of our bodies to bring us back to balance and health.
