YANOMAMI AMERINDIANS, VENEZUELA AMAZONAS. Serra Parima, Orinoco river basin. Portrait of a Yanomami boy The Yanomami continue to live as tribal farmers, practising an ecologically sound form of shifting cultivation, supplementing thier diet with fishing and hunting. They live in one of the most inaccessible regions of the Amazon, and of all the Amerindian tribes, the Yanomami have the least exposure to the modern world. Their future may now be threatened by diseases spread by illegal Brazilian gold miners.
