What can we learn from Buddhism to understand and respond to our ecological crisis? This question is the heart of David's focus, as I understand it. We started by describing his journey from a more mainstream American childhood to Zen Buddhism and forming the Rocky Mountain Ecodharma Retreat Center near Boulder, Colorado. Then we talk about humanity's disconnect from nature and his work to restore it, in the context of his Buddhist path. We also talk about reconnecting with nature, letting go of the cultural forces to disconnect. He shares his work to help people handle these problems and their grief. We talked about how we handle what we humans are doing to our world and what we're doing about it, including from a Buddhist perspective, using Buddhist practice.
