9 Easter Island

10 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

13 Tragedy of the Commons Garrett Hardin

14 FLT I can demonstrate the tradegy of commons through performing and analyzing lab results

15 Garrett Hardin – Economist
Authored essay in 1968 titled “The Tragedy of the Commons”. Focuses on: 1. environmental degradation population growth 3. limited natural resources 4. privatization of land

16 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.

17 What are common resources?
Air! No one owns the air-avail to all Water in oceans & rivers is avail to all. Fish of the sea avail to all. Note: First codified by Romans in 535 AD.

18 Common Resources

19 Common Resources



22 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.


24 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.

25 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.


27 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."

28 Checking for Understanding
For the next 26 seconds, review 3 main points discussed in this Power Point

29 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.

30 Sustainability… Meeting present needs of today’s populations without compromising the needs of future generations.

31 Standards of Sustainability= “SEE”
an extended social group having a distinctive cultural and economic organization Society Economy Environment Combination of all things & factors external to individuals or populations Production Consumption Distribution

32 Questions? How does Tragedy of the Commons ideas connect with the concept of sustainability? Explain. Does the “Commons” reflect utilitarian conservation or biocentric preservation?
