Easter Island (Rapa Nui) has gained recognition in recent years due in part to a book that used it as a model for societal collapse from bad environmental practices—ringing alarm bells for those concerned about the health of the planet today. But that’s not the whole story, says Dr. Chris Stevenson, an archaeologist who has studied the island—famous for its massive stone statues—with a Rapa Nui scientist, Sonia Haoa, and Earthwatch volunteers for nearly 20 years.
The ancient Rapanui people did abuse their environment, but they were also developing sustainable practices—innovating, experimenting, trying to adapt to a risky environment—and they would still be here in traditional form if it weren’t for the diseases introduced by European settlers in the 1800s.
“Societies don’t just go into a tailspin and self-destruct,” says Stevenson, an archaeologist at the Virginia Department of Historic Resources. “They can and do adapt, and they emerge in new ways. The key is to put more back into the system than is taken out.”
While evidence suggests the Rapa Nui people cut down 6,000,000 trees in 300 years, for example, they were also developing new technological and agricultural practices along the way—such as fertilization techniques to restore the health of the soil and rock gardens to protect the plants. As a result, every rock on Easter Island has probably been moved three or four times, Stevenson said.
