The Hadza are a tribe of hunter-foragers who live in Tanzania. Shani Mangola is a Hadza man who studied at the University of Arizona and went back to live among his people. The Hadza have been pushed off the land on which they used to live, and the wild game they used to hunt has become scarce. They now often rely on tourists for financial assistance. They are told by tour guides, "Don't use the phone. Just live like the Stone Age." Anthropologists also love to study them to understand how our ancestors lived in hunter-forager times. They discourage the Hadza from eating modern food, and compensate them with small gifts such as knives and blankets. One of the latest trends is harvesting fecal samples from the Hadza in order to use them to "rewild" modern gut microbiomes. Dr Keolu Fox, an anthropologist and genomics researcher at the University of California, San Diego, considers this "predatory and imperialistic", saying it's another example of Western researchers exploiting Indigenous populations who have no control over who owns or profits from the data that is gathered. --- Source: https://www.nytimes.com/2021/07/19/health/human-microbiome-hadza-rewilding.html
