Quoted: The tragedy of the commons is a type of social trap, often economic, that involves a conflict over finite resources between individual interests and the common good. It states that free access and unrestricted demand for a finite resource ultimately structurally dooms the resource through over-exploitation. The term derives originally from a comparison noticed by William Forster Lloyd with medieval village land holding in his 1833 book on population.[1] It was then popularized and extended by Garrett Hardin in his 1968 Science essay "The Tragedy of the Commons."[2] However, the theory itself is as old as Thucydides[3] and Aristotle.[4]
