If you haven’t heard of it, this island has a population that the world has collectively decided to leave alone, mostly because they have proven, on multiple occasions, that they absolutely do not want visitors. Like, arrow-to-death anyone attempting to land or even visit near their shores.
This probably cannot go on forever… but maybe, it could. Essentially, we are already implementing a ‘Prime Directive’ of sorts here. Would the 23rd, 24th, … centuries in Star Trek canon still have this little island on Earth, isolated from not just from Earth’s own unified Federation society, but from the greater Federation races? What steps would the Federation and Earth take to maintain their isolation and the ecosystem on which they depend?
Would make for an interesting episode, or at least a cool side-note reference in one :)
I imagine that the events leading up to the formation of the Federation would disrupt their way of life. Most notably, WWIII, which most likely could wipe them out. Assuming they remain somehow untouched, the eventual visible air traffic might draw out the more curious among their population.
I’m pretty sure there’s visible air traffic there today. Veer Savarkar International Airport is only ~30 miles away from North Sentinel Island, so they probably see planes on a daily basis.
