As a boy growing up on a ranch in Brazil, Sebastião Salgado witnessed firsthand the destruction of the native forest. As thousands of acres were cleared for herds of cattle that demanded more and more pasture for grazing, the landscape was inexorably transformed into a dust-filled plain. Because of this experience, Salgado decided to make the remote tribes of South America an essential element of "Genesis," his eight-year collaboration with Rolling Stone to document the planet as it looked at the dawn of time.
The first half of the Genesis project is on the Yanomami Indians, who are believed to be among the first inhabitants of South America. For the Yanomami, the forest is not just 'nature' but an all-important living entity that controls the destiny of the tribe.
