On this episode, Nate is joined by ER doctor, nuclear power advocate, and podcast host Chris Keefer for a broad ranging conversation including the basics of nuclear energy, how he engages with opposing opinions, and hypotheticals for a future medical system. Coming from a broad background, Chris understands what it means to have a human to human conversation and put together the pieces of our systemic puzzle in a clear and compelling way. What role could nuclear play for our future energy needs - and how are different countries making use of it today? How can we prioritize the health and safety of people under energetic and resource constraints? Most of all, how do we listen to others that we don’t agree with - regardless of the issue - to foster the diverse perspectives necessary to navigate the coming challenges of the human predicament?
