This week is a big one, so I want to start with a note that this conversation is deep, complex and not for the faint of heart. Dr. Zach Bush is a triple board certified physician who specialises in internal medicine, endocrinology and hospice care but who is also incredibly passionate about the ecological health of the Earth. We cover it all this week — birth, death, disease, the human microbiome, the genome, immunity, and the health of the Earth’s ecosystems. Dr Bush has been outspoken about some of the ways the medical system is failing with Covid-19 but this episode is so much more than that, our discussion goes beyond controversy and into the depth of how health and illness relate to spirituality, psychology and philosophy. Dr. Zach Bush presents a model of health that is regenerative and centres the health of humans within the health of the Earth.
