Outline
I.
Introduction to my topic, why it is
important, and my thesis.
a. Easter
Island, also known as Rapa Nui has long been a topic of study.
a.
It is located about 3,200 km West of
Chile (Foot, 12). In other words it is very isolated.
b.
It is approximately 64 square miles
(Foot, 12).
b. Studying
Easter Island is important because it is a small scale example of a society
collapsing due to the degradation of their environment, and those problems can
be related to the issues we are having with our environment today.
c. Thesis:
Easter Island collapsed before the European’s arrival due to deforestation and
overall degradation of the island’s environment which is attributed to overuse.
II.
Background: In order to support my
argument I must first establish my sources as reliable by giving their
background, as well as show my opposing sources backgrounds as not to be
biased. I will also briefly state their positions.
a. My
primary supportive sources are Jared Diamond, John Flenley, Kevin Butler, and
Paul Bahn.
a.
Jared Diamond is from the University of
California and is a world renowned geographer.
b.
John Flenley and Kevin Butler are from
Massey University.
c.
Paul Bahn has a Ph.D. from the
University of Cambridge.
b. My
primary opposing sources are Terry Hunt, Carl Lipo, and Paul Rainbird.
a.
Terry Hunt is from the University of
Hawai’i.
b.
Carl Lipo is from California State
University
c.
Paul Rainbird is from the University of
Whales.
c. My
primary sources support my thesis statement that deforestation was due to the
Islander’s overuse of the trees, and that their society collapsed before the
Europeans arrived in the late 1700’s.
d. My
opposing sources believe that rats and disease played a heavier role in
deforestation and population decline than they did, and that Easter Island did
not collapse until after the European’s arrival in the 1700’s.
III.
When Easter Island was settled, and
ongoing debate.
a. Opposing
sources argue that Easter Island was not settled until AD 1200 (Hunt, Lipo, Chronology, 85).
b. On
the other hand, John Flenley, Kevin Butler, and Paul Bahn show that Easter
Island was inhabited before that point in time (98). They then show that the
island was settled in AD 800 (Flenley, Butler, 101).
c. Helene
Martinsson-Wallin and Susan J. Crockford provide further evidence (Radiocarbon-dated
burned charcoal, sediment layers, rat bones, and bird bones) that Easter Island
was settled before AD 800 (5-7).
d. Thus,
I conclude that Easter Island was settled by approximately AD 800.
IV.
It is important to know what happened
with Easter Island’s population in order to understand the strains it put on
the island, and to later help emphasize the decline.
a. Originally
2 canoes with approximately 40 people settled on the island (Foot, 13).
b. They
built up around 1,233 houses, we can safely say about 1/3 of the houses and had
approximately 5-15 people per house, which means there were between
6,000-30,000 people at the island’s peak (Diamond, Collapse, 90).
c. Opposing
sources such as Hunt and Lipo believe the colonization date to be later and
thus estimate there were only 4,000 people at the population peak (Conflicting, 13).
V.
The involvement of rats with
deforestation is another big debate between my primary and opposing sources.
a. My
supporting sources argue that the rats had minimal involvement as they only ate
the seeds to the trees, and not the actual trees themselves.
b. Hunt
and Lipo believe rats had a huge impact on Easter Island’s forest (93).
c. Flenley
and Bahn show there is no way that rats could have been responsible for
deforesting Easter Island, or that they could have even had a substantial
impact (12).
VI.
The involvement of disease is highly
debated because disease was brought with the European’s in the late 1700’s.
a. Disease
could have contributed to Easter
Islander’s collapse (Koss, 548).
b. By
the time the European’s arrived on Easter Island, Easter Island was already
collapsing and thus disease could not have been the cause of the collapse.
c. This
leads us to the timeline of deforestation to show that disease/the European’s
arrival and impact did not cause the collapse of Easter Island.
VII.
The timeline of deforestation.
a. Easter
Island was covered by forest for as far back as we can tell before it was
colonized (Hughes, 1).
a.
Hughes is an emeritus professor from the
University of Denver Colorado.
b. Pollen
analysis also shows that prior to colonization the palm tree covered the island
(Foot, 15).
c. Stone
statues played a significant role in the deforestation of the island.
a.
They began building megalithic statues
around AD 1000 (Diamond, Collapse, 97).
b.
The Islanders moved their statues by
cutting down trees and rolling them into place with them (Hamilton, 172).
c.
Approximately 900 statues have been
inventoried, approximately 300 of which were giant (Diamond, Revisited, 1693).
d. Around
AD 1280 the islanders began chopping down more and more trees and burning them
for intensive agricultural purposes (Foot, 15), as shown by radiocarbon-dated
charcoal, burned wood remnants and burned stumps (Diamond, Revisited, 1692).
e. All
of this led to a significant loss of the palm canopy that once covered the
Island.
f. By
AD 1450 the palm tree that was the most predominant on the island was almost
entirely gone if not gone (Diamond, Revisited, 1692).
g. By
AD 1650 other large trees were almost if not entirely completely gone (Diamond,
Revisited, 1692).
h. Around
AD 1600 Easter Island’s population peaked, and then suddenly collapsed right
after (Foot, 13). This shows the population had begun collapsing over 100 years
before the European’s arrived.
VIII. The
effects of deforestation are important to show so that we can understand why
they caused Easter Island to collapse.
a. One
of the primary consequences was food scarcity.
a.
Though they tried adapting to use lithic
multh agricultural methods, they still could not produce as much food as when
the trees protected the soil, and held moisture and other nutrients in the soil
(Diamond, Revisited, 1692). Lithic mulch aided the soil in holding water,
preventing evaporation, and preventing erosion, but was not as effective as the
trees (Stevenson).
b.
Birds once supplemented the Islanders
food supply, but with no trees as safe havens they went extinct shortly after
deforestation (Foot, 15). Additionally the bird droppings that once provided
nutrients to the soil were severely diminished (Foot, 15).
c.
The Islanders could not build canoes to
hunt porpoises in the deeper seas without wood and thus lost that food source
(Foot, 15).
d.
All their meat was cooked over firewood
from Easter Island’s forests, until they had none, which made food preparation
more difficult (Diamond, Collapse, 105).
e.
The sap from the palm trees was another
food source they lost once the island was deforested (Foot, 15).
b. The
Islanders had no wood to build boats to leave the island once their population
peaked and they did not have enough food (Stevenson).
c. The
Easter Islanders turned to cannibalism due to their lack of food (Foot, 15).
d. The
presence of severely damaged bones and legends of such warfare during AD
1650-1680 suggest a society in serious trouble collapsing into civil war
(Flenley, Butler, 101). There was also an abundance of spear heads found that
were dated prior to European interaction (Flenley, Butler, 101).
IX.
When the European’s arrived they found
an already collapsing society.
a. They
found approximately 1,400-1,600 people living on the Island (Diamond, Collapse, 109).
b. They
described the people as lean, tired, worn, and many of their statues had been
destroyed (Diamond, Collapse, 109).
c. Some
accounts of the European’s arrival state that the island had a few trees on it,
but others say there were no trees to be found (Hughes, 4).
X.
Conclusion: What does all this
information mean?
a. Individually
these instances are only suggestive that Easter Island collapsed, however, together
they provide a massive wall of evidence showing that Easter Island collapsed
before the Europeans arrived in the late 1700’s (Flenley, Butler, 102).
b. Rats
only reduced the trees ability to replenish they were not the underlying cause
of deforestation.
c. Because
this shows that Easter Island collapsed before the European arrival in the late
1700’s there is no way disease could have been responsible for the collapse of
Easter Island as Hunt and Lipo argue.
d. Easter
Island’s peak population was approximately 6,000-30,000 according to Jared
Diamond earlier (Collapse, 90), and
it was approximately 4,000 according to Hunt and Lipo (Conflicting, 13), given
either of these numbers, how could anyone say that the population had no
collapsed when the Europeans arrived and found a mere 1,400-1,600 people?
e. Easter
Island is a small scale demonstration of what could happen to our society if we
do not make changes. The Islanders could not leave the island once they had
depleted their environment, and on a larger scale, we cannot leave ours if we
repeat those same mistakes.
