Easter Island
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

Tragedy of the Commons
Garrett Hardin
FLT

can demonstrate
the tradegy of
commons through
performing and
analyzing lab results
Garrett Hardin – Economist
Authored essay in 1968 titled
“The Tragedy of the Commons”.
Focuses on:
1. environmental degradation
2. population growth
3. limited natural resources
4. privatization of land
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.
What are common resources?
Air! No one owns the air-avail to all
2. Water in oceans & rivers is avail to all.
3. Fish of the sea avail to all.
Note: First codified by Romans in 535
AD.

Common Resources
Common Resources
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."
Checking for Understanding
 For
the next 26 seconds,
review 3 main points discussed
in this Power Point
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.
Sustainability…
Meeting present needs of
today’s populations
without compromising the
needs of future
generations.
Standards of Sustainability= “SEE”
an extended social group
having a distinctive
cultural and economic
organization
Combination of all things
& factors external to
individuals or
populations
Society
Environment
Production
Consumption
Distribution
Economy
Questions?
1.
How does Tragedy of the Commons
ideas connect with the concept of
sustainability? Explain.
2.
Does the “Commons” reflect utilitarian
conservation or biocentric
preservation?
