We take our civilization for granted.  But it’s fragile and pushing way beyond sustainable limits.  How and why do civilizations collapse?  In this program, we’ll hear from specialists who studied the end times of the Indus civilization of India and Pakistan, and the Maya of Central America.  Then we’ll wrap up with a tough solution for our tough problems: a new book outlines how we could use World War Two style mobilization to save the climate and the ecosphere from their developing collapse.  Our three guests are Cameron Petrie, Takeshi Inomata, and Laurence Delina.
