Ep 51 Ch 17 "Unsustainable" Part 1

What does the watchword of today "sustainable" really mean when taken seriously? In this episode we compare two titans of science communication: David Attenborough and Jacob Bronowski - for although they have inspired generations of scientists and those interested in science, their underlying philosophies could not have been more different. What are those philosophies and what consequences could they have if they were to drive actual policy? Also - a diversion on aspects of Australian and British history.
