North Sentinel Island has spear-era tribe – can we truly keep them isolated? We might think that’s in their best interests – but with only 100 or so of them left, one disease could wipe them all out. Their entire culture would be lost. And as much as “educated well-meaning folk” might want to let them live their lives, how can we ensure money-hungry “extreme safari groups” won’t start up tours here, and have billionaire tourists feeding them candy from van windows? Sadly, it’s happened elsewhere.
