Unnatural Histories

It takes a new look at three of the world's wildernesses; the Serengeti, Yellowstone National Park and the Amazon and discovers that far from being wild and untouched, each has been shaped over time by man.

Investigates how the Serengeti became wild through the actions of a colonial disease that emptied the land of the people and livestock that had lived there for hundreds of years.

However, the discovery of geoglyphs uncovered following deforestation in the 1970s and terra preta, provide growing evidence for ancient cities in the heart of the 'virgin forest'.
