Given recent events, I thought a revisit of "Tragedy of the Commons Restated" written by Jay Hanson 12 years ago, might an appropriate Campfire topic.

A "commons" is any resource used as though it belongs to all. In other words, when anyone can use a shared resource simply because one wants or needs to use it, then one is using a commons. For example, all land is part of our commons because it is a component of our life support and social systems.

A commons is destroyed by uncontrolled use—neither intent of the user, nor ownership are important. An example of uncontrolled use is when one can use land (part of our commons) any way one wants.
