Survival International has released amazing photographs of an uncontacted tribe in the Amazon in Brazil.

Researchers have produced aerial photos of jungle dwellers who they say are among the few remaining peoples on Earth who have had no contact with the outside world.

Taken from a small airplane, the photos show men outside thatched communal huts, necks craned upward, pointing bows toward the air in a remote corner of the Amazonian rainforest.

The National Indian Foundation, a government agency in Brazil, published the photos Thursday on its Web site. It tracks “uncontacted tribes” — indigenous groups that are thought to have had no contact with outsiders — and seeks to protect them from encroachment.

More than 100 uncontacted tribes remain worldwide, and about half live in the remote reaches of the Amazonian rainforest in Peru or Brazil, near the recently photographed tribe, according to Survival International, a nonprofit group that advocates for the rights of indigenous people.

“All are in grave danger of being forced off their land, killed or decimated by new diseases,” the organization said Thursday.

Some news sources report the uncontacted tribe are Envira Indians. Finding “uncontacted tribes” in the Amazon begs the question. Should they be contacted? Should they be protected from contact?

Dramatic photographs of previously unfound Amazon Indians have highlighted the precariousness of the few remaining “lost” tribes and the dangers they face from contact with outsiders.

The bow-and-arrow wielding Indians in the pictures released on Thursday are likely the remnants of a larger tribe who were forced deeper into the forest by encroaching settlement, experts said.

Rather than being “lost”, they have likely had plenty of contact with other indigenous groups over the years, said Thomas Lovejoy, an Amazon expert who is president of The Heinz Center in Washington.

“I think there is an ethical question whether you can in the end keep them from any contact and I think the answer to that is no,” Lovejoy said.

“The right answer is to have the kind of contact and change that the tribes themselves manage the pace of it.”
