Imagine…

Hardin’s parable involves a pasture "open to all."

He asks us to imagine the grazing of animals on a common ground.

Individuals are motivated to add to their flocks to increase personal wealth.

Tragedy of the Commons

Every animal added to the total degrades the commons a small amount.

Although the degradation for each additional animal is small, the gain in wealth for the owner is greater.

Tragedy of the Commons

As selfish stewards, each owner adds another to their flock and the pasture.

If all owners follow this pattern the commons will ultimately be destroyed.

Tragedy of the Commons

As a result, the commons were overgrazed and degenerated to the point that they were no longer able to support the villagers' cattle.

This failure of owner of these private lands to preserve the natural resources is known as "the tragedy of the commons."

What is the “tragedy”?

“We can avoid tragedy only by altering our values.” Hardin, 1968

This means we can change the way we live (sustainably) by preserving our natural resources—even in the private sector.
