The rise and fall of Easter Island seem extremely objective to the whole of human society, so objective that it's almost indifferent.
This isolated island became an excellent "experimental field."
Before modern times, no outsiders had ever set foot on Easter Island. On this remote island, the sediments at the bottom of the ponds were completely undisturbed—the topmost layer being the closest to the present day, and the lowest layer being the farthest from it.
In the nineties, the latecomers of the technological boom, after exploring and studying the distribution of plant pollen in the sediments at the bottom of the island's ponds, coolly and clearly saw the entire course of over a thousand years.
Before all such evidence, it was like sitting in front of a TV, watching the entire island transform from a lush forest into a sparse grassland.
