On the other hand I believe that the global effects of fossil fuel use make a far more persuasive and powerful argument. An ever tightening series of booms and busts based on oil prices, increasing job losses, stagnant or decreasing wages, accelerating inequality, massive default on debt - that is what we are looking at when we look at the bottom of the barrel.
One of the best examples of a human built commons is language. A language is a commons, because everyone in a certain locality can speak it, everyone uses it everyday, and the evolution of the language, it’s words, pronunciation, grammatical rules, etc., are all collectively determined.
I think it is important to understand what the difference between humans and our primate relatives is and how it came about. A tall order, I know, but the more we know the real reason for the difference, the more consciously we can use this knowledge to adapt to the new challenges that now face us.
All other primate species are organized according to dominance hierarchies. The biggest strongest male gets the pick of the females and the choicest food.
In dominance hierarchies information is sequestered to serve or to avoid serving the interests of the dominant male. This results in a lot of wasted resources that are used solely to keep the majority impoverished while the dominant and his confederates get the lion’s share.
Before the crucial development of human egalitarianism sharing information was not as desired a trait. For the dominant, language would have made it harder to keep what he had to himself. And it would have been the same for the subordinate. For the subordinate to share would have meant giving up more of what she had appropriated to the dominant.
