At the same time, an old plan to build five major dams along the Xingu river has been resurrected and will threaten the livelihoods of the 18 tribes of the region. The original plan was shelved in 1989 following massive international outcry.
The remote Enawenê Nawê number just 420 and live largely by fishing. They are protesting against plans by soy companies led by the world's largest soy producers, the Maggi family, to dam the Juruena river for hydroelectric power for the industry.
The Enawenê Nawê, unlike most Amazon tribes, eat no red meat. The dams would severely disrupt the breeding cycles of the fish they rely on, and destroy their livelihood and unique rituals associated with the fishing cycle.
The Enawenê Nawê have said, "The dams will bring our death, as they will raise the uncontrollable anger of the spirits." They have written an open letter expressing their anger.
The Xingu dams project was abandoned in 1989 after the Kayapó tribe staged huge protests and captured the attention of the world's media. The Kayapó are now seeking support for another campaign against the Xingu dams.
"Damming the Enawenê Nawê's river," said Survival's director, Stephen Corry, "would spell disaster for this unique tribe. The dams must not go ahead. As for the Xingu river, it's hard to believe that the Brazilian government is even contemplating this disgraced project again."
Survival is an international group dedicated to help tribal people to keep their lands and maintain their lifestyle.
