First-ever photos of ‘uncontacted’ group in the Amazon

Over the weekend, The Guardian published the first known photos of an uncontacted community living in the Amazon. The group is called the Massaco, named after a local river. But what they call themselves, like many other details, remains unknown. The World’s Host Marco Werman spoke to John Reid, one of the series’ co-authors, about Brazil’s policies to avoid direct contact with communities like the Massaco.
