In this episode we look at what we’re calling “expansionism”, how the natural tendency of a species to expand into its niche, is unnaturally extended beyond those natural limits by humans. Pursuing this thoughtline brings us to a discussion of World War II as a historical precedent for our world in crisis today, particularly the theme of the war mobilization as precedent for addressing the current climate emergency.
