When is it Legitimate to Exploit Remote Communities?

Criticism of explorer Benedict Allen, rescued in Papua New Guinea, raises an important question: when is it legitimate to travel to remote communities? (Mary-Ann Ochota What's the difference between explorers, anthropologists and tourists? Guardian, Thursday 23 November 2017). I'd say it is a similar question to what the difference is between archaeologists, collectors and sensation seekers in the exploitation of the fragile and increasingly finite archaeological record. I do not think that is one that the British archaeological establishment will be looking at with any alacrity or academic care.
