If people believe that sustainability and economic growth are incompatible then why would their place their bets with economic growth?
But just in case I will post any interesting responses I get from elsewhere here.
UPDATE: I haven’t yet gotten a satisfying answer, bit I think the simplest answer is probably correct. Simply put the people I describe above either don’t understand what sustainability means, or don’t know what the implications of having an unsustainable civilization are.
If this is true, then the question becomes how do we explain sustainability in a way that makes the implications of unsustainability stick.
