[The 17th in a series of essays, On Climate Truth and Fiction, in which I raise questions about environmental distress, the human experience, and storytelling. It first appeared on 3 Quarks Daily. The previous part is here.]
The peopling of Polynesia was an epic chapter in world exploration. Stirred by adventure and hungry for land, intrepid pioneers sailed for days or weeks beyond their known horizons to discover landscapes and living things never before seen by human eyes. Survival was never easy or assured, yet they managed to find and colonize nearly every spot of land across the entire southern Pacific Ocean. On each island, they forged new societies based on familiar Polynesian models of ranked patrilineages, family bonds and obligations, social care and cohesion, cooperation and duty. Each culture that arose was unique and changeable, as islanders continually adjusted to altered conditions, new information, and shifting political tides. Through trial and hardship, most of these civilizations—even on some of the tiniest islands, like Anuta and Tikopia, discussed in the preceding essay—persisted for centuries or millennia, up to the present day. But others faltered, failing to thrive or even to maintain continuity.
Most Polynesian societies that met the tragic fate of famine and disintegration were on remote islands measuring but a few square miles. But size alone was not the decisive factor. In fact, the most famous case occurred on a substantially larger island of about sixty square miles, called Rapa Nui1, widely known as Easter Island. Despite its relatively generous size, Rapa Nui suffered certain drawbacks. Owing to its more southerly latitude, outside the tropics, it was cooler, drier, and windier than most Polynesian islands—suboptimal conditions for some of their primary crops. Freshwater sources were also few, relative to the island’s size, and sometimes difficult to access. And the cooler surrounding ocean didn’t support the shallow reefs more common to tropical seas, making the islanders’ survival dependent on deep-sea fishing.
On the other hand, when the migrants first arrived, almost eleven hundred years ago, the pristine island was crowned with a dense forest of enormous trees, including a colossal species of palm found nowhere else on Earth, as well as other edible and useful plants. Small fish and shellfish could be gathered along the coast. In addition to several species of non-migratory birds inhabiting the forestland, seabird rookeries crowded the surfaces of rocky mounts just offshore. And the island’s three dormant volcanoes provided great quarries of stone suitable for making fine tools. The fate of the Rapanui people was in no way preordained.
