Mona Lisa

Garrett Hardin was a professor of biology and environmental studies at UC Santa Barbara. His “commons” was a metaphor drawn from the traditional English practice of shared grazing and agricultural land to which all members of a community had access. Commons were inherently prone to abuse, Hardin argued, because every user of the commons will exploit it to maximize personal benefit without regard to the other users, leading ultimately to the collapse of the commons as a useful resource. Hardin extended the metaphor of the commons to include all natural resources, including the air, water, other species, even the entire Earth. The tragedy of Hardin’s expansive commons was the inexorable march to environmental doom, driven by the folly of human freedom.
