Jacopo Simonetta – The other side of the global crisis: entropy and the collapse of civilizations

When we discuss the impending crisis of our civilisation, we mainly look at the resources our economy need in a growing quantity. And we explain why the Diminishing Returns of resource exploitation pose a growing burden on the possibility of a further growing of the global economy. It is a very interesting topic, indeed, but here I suggest to turn 180 degrees around and take a look at the “other side;” that is to what happens where the used resources are discarded.

Eventually, our society (as any other society in history) is a dissipative structure. It means that it exist only because it is able to dissipate energy in order to stock information inside itself. And there is a positive feedback: more energy permits to implement more complexity; and more complexity needs, but it also permits a larger energy flow. This, I think, is a crucial point: at the very end, wealth is information stocked inside the socio-economic system in different forms (such livestock, infrastructures, agrarian facilities, machines, buildings, books, the web and so on). Human population is peculiar because it is a large part of the information stocked inside the society system. So, from a thermodynamic point of view, it is the key part of “wealth”, while from an economic point of view people can be seen as the denominator of the global wealth.
