Hardin

The article titled "The Tragedy of the Commons" by Garrett Hardin was published in Science, New Series, Vol. 162, No. 3859 on December 13, 1968, spanning pages 1243-1248.
It discusses the conceptual notion that certain problems, particularly those related to population growth and resource management, do not have purely technical solutions requiring only advancements in science and technology; instead, they necessitate a reevaluation of moral and ethical values.

Population Problem: Hardin claims there is no technical solution to the problem of population, which requires a fundamental extension in morality.
Technical Solution vs. Moral Judgement: A technical solution is defined as one that necessitates only changes in scientific techniques, without any alterations in human values or moral beliefs. Hardin emphasizes the distinction in discussions regarding societal problems and posits that many look for scientific or technological quick fixes rather than wrestling with the ethical implications.

Hardin highlights that some issues, termed "no technical solution problems," require more than facts and figures; they necessitate deeper human introspection and ethical decision making.
Example: The game of tic-tac-toe illustrates this point — winning involves abandoning conventional play or the agreement of the game itself. Similarly, the population problem cannot be solved merely through technological means.

Malthusian Theory: Reference to Malthus' idea that population tends to grow geometrically (exponentially), while the capacity of the planet's resources is finite. Thus, increasing population leads to decreased per capita resources which must ultimately equal zero at some point.
Maximization of Goods vs. Population: Hardin claims that maximizing population does not correlate with maximizing goods or quality of life. He suggests that any effort to increase population density beyond a sustainable limit will inherently reduce the overall quality of life.
Biological Foundations: Every organism, including humans, requires energy to maintain life. Maintenance requires about 1,600 kilocalories daily. Any attempt to maximize population leads to a decrease in enjoyment and organisms must make choices that significantly limit their quality of life.

Hardin explains the principle of "the tragedy of the commons" using the pasture analogy where individual herdsmen seek to maximize their gain by increasing herd size without regard for overall sustainability, ultimately leading to resource depletion for all.
Positive and Negative Utility: For each herdsman's decision to add additional cattle, the immediate benefits (positive utility) outweigh the shared detriments of overgrazing (negative utility), driving a collective tragedy.
Psychological Denial: Observations are made on tendencies of individuals to benefit at the individual’s expense while neglecting the long-term societal implications.

Potential misuse of common areas, such as national parks, oceans, and public lands, reveals a consistent theme: without restrictions on access or an appropriate management system, exploitation of resources leads to degradation.
Pollution: Hardin discusses pollution as a tragedy of the commons. The act of discharging waste into common areas benefits individuals but harms society. The rational breakdown leads to individuals over-utilizing common resources, leading to widespread negative consequences.
Moral and Legal Frameworks: He suggests that society’s current moral framework is ineffective at managing these commons, pointing towards necessary policy changes and regulation to curtail pollution and resource overuse.

Hardin introduces the notion that while freedom to choose may have been the ideal, certain freedoms, like breeding, must be curtailed to avoid collective ruin.
Mutual Coercion: He posits that mutually agreed-upon coercion may be necessary to create responsibility; avoiding the pitfall of individual interests over societal needs.
Education: Hardin emphasizes the importance of constant education to reappraise the understanding of commons and to counteract misconceptions.

Hardin advocates for setting limits on population growth and urges recognition of the necessity to transition from a commons-based approach to managing resources effectively.
He critiques existing moral frameworks and calls for a reevaluation of societal ethics and responsibility, especially concerning resource management and population control.
