Esty Dinur returns from her time away on assignment, straight into the first week of WORT’s winter pledge drive. Her guest is Professor Anitra Nelson, researcher in the Centre for Urban Research at RMIT University in Australia. Dr. Nelson recently wrote about the necessity of sustainable housing and shared living spaces in her book, Small Is Necessary: Shared Living on a Shared Planet, which was just released this year from Pluto Press and University of Chicago Press.
