Introduction.

The environment in which we live today has been subject to mans influences ever since he evolved. The question is have any lessons been learned during this journey through the ages. The examples discussed here show how populations from different areas have been affected detrimentally both with and without outside influence. All have been subjected to varying degrees of human tragedy and shows clearly how man has been unable to alter the roller coaster ride of progress so as to benefit him.

Hopefully in this modern world people will start to understand the ethos of some of the more environmentally aware nations and follow their lead. If not, one day the point of no return will be reached and history will record that the people of the 21st century failed to prepare its populations for future sustainability.

The choice of the topic ‘Environmental lessons from history’ was an attempt to study as broad banded a subject as possible with the hope of finding a general link between the facts uncovered. I t was further decided that the selection of individual topics to research should be as unfamiliar as possible to us to avoid preconceived conclusions. This took each author on a voyage of discovery to seemingly unconnected geographical areas and their historical backgrounds. Intermediate communication between the group members led to a network of ideas and general conclusions being formed. It was soon apparent that the particular subjects that we had chosen to study had strong links with each other and moreover parallels with current day affairs of the world.  

Rapa Nui.

Introduction.

“In the middle of the Great Ocean in a region where no one ever passes, there is a mysterious and isolated island; there is no land in the vicinity and, for more than eight hundred leagues in all directions, empty and moving vastness surrounds it. It is planted with tall, monstrous statues, the work of some now-vanished race, and its’ past remains an enigma”.

Thus wrote Pierre Loti, a naval cadet, in his journal L`ile de Paques of 1872, whilst visiting Easter Island on board the French frigate La Flore. (quoted in Orliac and Orliac, 1995).

It would seem that before any comprehensive discussion of Easter Island can begin one has to be aware of the remoteness of this land and the vegetation, inherited by its’ current inhabitants. Lying 1400 miles south-east of Pitcairn, the nearest inhabited island, and 2340 miles from Concepcion, in Chile, its’ closest continental landfall, Easter Island is a small delta shaped volcanic peak covering an area of 64 square miles. Described by modern writers as treeless and barren it has an average rainfall of 47 inches and a temperature range of 64o f in winter to 74o f in summer, a fairly equitable climate, with perhaps one drawback being the winds that often blow onshore. (Bahn and Flenley, 1992).

Visitors arrive

It is now believed by most students of Rapa Nui, to give the island its’ local name, that the original settlers came from Polynesia, led by a great warrior chief named Hotu Matua. Katherine Routledge, author of The Mystery of Easter Island in 1919, spent 17 months there and was told of 57 generations of kings ruling the Island since Hotu Matua’s first coming, by canoe, with his people from the southern seas. (Ref. Bahn and Flenley, 1992). Thor Heyerdahl, who visited the island in the 1950’s, presents a different idea of travellers coming from South America arriving there (Heyerdahl, 1958), whereas Erik von Daniken, in Chariots of the Gods, in 1967, recounts a tale of extra- terrestrials influencing the development of Easter Island. Both men seem to attempt to make the facts fit their theories, and it is perhaps important to establish in one’s mind the more than probable origin of the early inhabitants (Orliac and Orliac, 1995). Under the guidance of Tangaroa, the creator of all, maybe 100 Polynesians came upon this far-flung corner of their world in about 450A.D., whether by luck or judgement, island legend can not recall. They were thought to be from the Honga Clan. In John R. McNeil’s, The Face of Earth, a portmanteau biota is spoken of in the chapter written by (Hughes 2000), who is a leading authority in Polynesian culture. This would have led to certain grains for planting being introduced to Rapa Nui. The Polynesian rat, an edible mouse-sized rodent would have been introduced as well, he states. This portmanteau would supplement the natural bounty of the island and was an essential component of this seafaring era. (Hughes, 2000).

For many centuries not much is known or recorded of the prehistory of this newly borne mini-civilisation although it appears from later events safe to conclude that the islanders flourished in numbers and culture. Pollen analyses recorded in John R. McNeil’s book and attested to by botanist John Flenley, who visited the site in the 1980’s, show the prevalence of the wine palm, more or less identical to a species now native to Chile. This tree can grow up to 80ft. tall and have a diameter of 3ft. Sediments have shown heavily forested areas of land around 800 A.D.. Indeed John Flenley and Paul Bahn, in botanical terms, goes on to argue the case that only where saline spray might inhibit growth would there not be an abundance of many forms of low growing to medium-sized tree type vegetation. (Bahn and Flenley;1992).

 

Eyes skyward

Most modern day writers on the subject tend to agree that the statue (or Moai) sculpting and erecting, that the island is famous for, had started by 1100 A.D. The tree clearances, which were connected to the monument making, as will be seen, commenced around 850 A.D. (Bahn and Flenley; 1992). This is once again gleaned from botanical evidence. There are so many theories about why the statues were originally made, what their purpose was and how they were moved into position, that it might be worth relating the words of Jo Anne van Tillburg, an archaeologist from UCLA, who was the recent author of Easter Island, Archaeology, Ecology and Culture (van Tillburg; 1998). “The remains are so visible there on the surface and the place is so small. But I’ve been working here 15 years and I have more questions now than answers”.

In his book, Easter Island, Earth Island, Paul Bahn puts forward the argument that the different nobles on Rapa Nui, together with the priests, started encouraging the people to erect the standing figures. As the centuries passed by competition to build bigger and more elaborate carvings seemed to grow, with carvers being commissioned to create groups of statues on platforms, or Ahus, to give them their local name. The carving took place around the Ranu Raraku quarry where the volcanic basalt tuff was sculpted in situ before being moved to designated resting- places, in statuesque form. The importance of the carvers was acknowledged by dint of the fact that all sustenance was supplied to them by the many farmers and fishermen on the island. The question must be posed as to why this work was undertaken to such an extent. In seeking the answer to this perhaps one should look towards the very modern evidence of fragments of eyes made of white coral found in1978 by Sonia Haoa, a native archaeologist. She fitted a 14-inch oval with a red scoria pupil centre into one of the empty eye sockets of a fallen statue (Bahn and Flenley, 1996).

The figures had always stood facing inland but up till that time no traveller to the land had ever mentioned anything about their gaze. In fact in 1780 the French Comte de la Perouse, who visited the island in that year, had commented in his journal about the apparently sightless nature of the giants (Orliac and Orliac, 1995).

What it must have been like to be the inhabitants living on an island where tales of such overwhelming solitude must have drifted down through the hundreds of years, can only be imagined. They thought they were the last people on earth conjectures Paul Bahn. Why not then build huge images looking heavenward to seek an answer, from the gods, as to what might be in store for their remote civilisation? When no answer comes, construct more noticeable figures with colours engrained and adornments, such as the hats, or ‘pukao’ placed on later statues. The facing of the moai could represent the thinking of a people of such spectacular insularity; protective of their island but still wondering about their own mortality. Man, throughout history has always seemed very unaccepting of any form of marking time in history, perhaps mistaking settled guardianship of current resources as stagnation.

From forest to famine

The debate as to how the statues were moved to their chosen sites has been as contentious as any issue concerning Easter Island. William Mulloy (ref. Orliac and Orliac, 1995) an engineer who visited in the 1950’s and who is the source of many literary discussions on the subject, has favoured a wooden sled theory using the large wine palms as flexible supports for the horizontally transported carvings. Ropes cut from the triumfetta shrub, for lashings, completed the picture of mobility of the up to 60-ton giants. Different images of conveyancing have been discussed by Katherine Routledge (ref. Bahn & Flenley, 1996) and Thor Heyerdahl of an upright rolling technique on logs, and semi-walking once again using the palm as protection against damage (Heyerdahl, 1959). All theories point to a fairly speedy destruction of the island’s natural vegetation. John Flenley indicates a complete clearance of the main forest in the middle of the island by 1400 A.D. (Bahn & Flenley, 1992).

More and more statues were being produced at the quarry, far outstripping the distribution of the carvers’ products. Over 300 of the 900 statues found on Rapa Nui, to this day still lie in Rano Raraku, semi-buried. At this time the population had expanded to many thousands. In 1600 A.D. the number of people was thought to be at its’ height; certainly in excess of 8,000. Katherine Routledge even estimated the figure to be between 37,000 and 52,000 having been told that stories abounded in ancient legend of the ancestors at that time being as “thick as grass”. Grass may well have been a good analogy to use, because at this stage most other types of vegetation had almost certainly disappeared. The statue building had demanded the ultimate incursion into this natural resource. The palms were soft and did not endure the heavy loads for long, being burnt into the figures to form extra designs as a final utility (Bahn & Flenley, 1992).

Soil erosion occurred and increasing damage was being done by the Polynesian rat, introduced 1000 years before, as the ecologist John R. McNeil evidences (Hughes, 2000). People were not being able to support themselves so well, the carvers were supporting nobody and the situation was becoming increasingly desperate (Hughes, 2000).

 

“Then one day the blows of the adze on the rock face fell silent. They fell silent suddenly, for the tools were left lying and many of the figures were only half finished. The sculptors disappeared into the dark mists of antiquity” (Heyerdahl, 1959).

By the time the Dutch commander Jacob Roggeveen anchored his ship off Easter Island in 1722 the inhabitants who came to greet him and his crew, had become “so bold that they took the hats and caps of the sailors from their heads and jumped with their plunder overboard” he wrote in his journal. They had probably seen no outsiders for almost 1300 years but they showed little fear (Orliac C. & M.; 1995).

Bones and dust

The Dutchmen departed and it was not for another 50 years that two ships under the command of Felipe Gonzalez ventured to the island again. When the Spanish captain observed the total lack of lumber available his comment of “Not one plank” summed up a desolate scene. Captain Cook’s visit, four years later, led to a comment in his journal – “Here is no safe anchorage no wood no fuel; nor any fresh water worth taking on board”(quoted in Orliac and Orliac, 1995). By this time many of the statues had been pulled down, many of them deliberately beheaded by placing small rocks where their necks impacted on the ground. A new and very different ‘birdman culture’ had emerged, based on a back to nature type philosophy. Katherine Routledge researched the birdman culture, which started around 1760. Many carvings relating to it were found around the island and 480 pictures of frigate birds have been identified. Instead of the phallic statues, of former times, goggle-eyed smaller carved wooden figures appeared (Bahn & Flenley, 1992). Most natural resources had been used up and people were starving They had taken to living in caves, and closely guarded what little they had. Tales of human sacrifices, associated with the birdman culture and even cannibalism filtered down through later times. In 1780 La Perouse noted that the people had “no chief” (quoted in Orliac and Orliac, 1992), indicating that the priesthood and nobility had ceased to have influence, and probably no longer existed. Survival of the fittest seemed to have taken over.

Fallen idols

The 19th. Century saw slave traders start coming to Easter Island and many of the local people, whose numbers had already dwindled, were captured and taken to the guano mines in South America. In addition the slavers introduced livestock and rats, which devastated the remaining vegetation. In 1872, after a smallpox outbreak, Pierre Loti commented on the fact that parts of the island looked like a vast ossuary, with human bones lying in view (quoted in Orliac and Orliac, 1995). In 1860 Christian missionaries brought some stability to the island, but soon after, with further enslavements ...
