  7. 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.

  8. 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.

  9. 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.

  10. 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."

  11. 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.
