It turns out that there were about nine different environmental factors -- some, rather subtle ones -- that were working against the Easter Islanders, and they involve fallout of volcanic tephra, latitude, rainfall. Perhaps the most subtle of them is that it turns out that a major input of nutrients which protects island environments in the Pacific is from the fallout of continental dust from central Asia.
Er waren ongeveer negen verschillende milieufactoren, sommige erg subtiel, die tegen de Paaseilanders werkten, zoals bijvoorbeeld neerslag van vulkanisch as, breedtegraad, regen. De meest subtiele is misschien nog voedingsstoffen die het milieu van de Pacifische eilanden beschermt, afkomstig van de droge neerslag van continentaal stof van centraal Azië.
