Dave Pollard is talking about a book by Jim Merkel, Radical Simplicity.

"In the face of looming ecological disaster, many people feel the need to change their own lifestyles as a tangible way of transforming our unsustainable culture. Radical Simplicity is the first book that guides the reader to a personal sustainability goal, then offers a process to monitor progress to a lifestyle that is equitable amongst all people, species, and generations. It employs three tools to help readers begin their customized journey to simplicity."

Sounds fascinating.
