 Well, you can't run a world of eight billion people and increasingly tight global resource limits by having everybody Just work on their own and try and have a economy that is self-sufficient at home We need a globalized economy We need a globalized resource management to make that happen and geopolitics is the way we manage that If countries can't work out how to work with each other if they can't build institutions to cooperate Then there is no sustainability So perhaps the other way around is geopolitics is the heart of sustainability because without geopolitics there is no chance of sustainability
