The moai (statues) pictured above are on Easter Island (Rapa Nui) off the coast of Chile. The island is famous for its statues, its remoteness, as well as its ecological collapse. A once thriving civilization of tens of thousands of people built, moved, and erected the nearly 100 ton statues without the aid of modern technology. However, that same civilization consumed too many resources and left the island treeless, nearly birdless, and fell into clan warfare and starvation. The once mighty population dwindled to less than a couple thousand by the 1700s

what does commons mean
What does commons mean?

“Held in common” means the resource is owned by:

  • No one…or
  • Owned by a group

=all who have access to the resource.

imagine
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 commons1
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 commons2
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 commons3
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."

Checking for Understanding
  • For the next 26 seconds, review 3 main points discussed in this Power Point
what is the tragedy
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.
