The Amazon rainforest is the epitome of a last great wilderness under threat from modern man. It has become an international cause celebre for environmentalists as powerful agricultural and industrial interests bent on felling trees encroach ever deeper into virgin forest. But the latest evidence suggests that the Amazon is not what it seems.
As more trees are felled, the story of a far less natural Amazon is revealed - enormous manmade structures, even cities, hidden for centuries under what was believed to be untouched forest. All the time archaeologists are discovering ancient, highly fertile soils that can only have been produced by sophisticated agriculture far and wide across the Amazon basin. This startling evidence sheds new light on long-dismissed accounts from the very first conquistadors of an Amazon teeming with people and threatens to turn our whole notion of wilderness on its head. And if even the Amazon turns out to be unnatural, what then for the future of wilderness?
On December 26, 1541, Francisco de Orellana sailed up the newly discovered Amazon River with the Dominican Gaspar de Carvajal who chronicled the expedition. De Caravajal wrote of vast cities with roads and highways, and yet they had all disappeard within 20 years. The book "Relacion del Descubrimiento del Rio Grande de las Amazonas" was not rediscovered until 1895 but was considered to be primarily myth and fabrication.
