Prudent versus profligate modes of resource use
Societies use natural resources either prudently, with restraint enforced by local knowledge, social norms and a long-term stake in the resource, or profligately, extracting as fast as possible because costs can be pushed onto others or onto distant places. Which mode a society is in depends less on culture or technology than on whether users stay tied to one resource base over time. Resource conflict intensifies when a profligate mode is laid over communities that were running a prudent one.
