By that logic, uncontacted tribes shouldn't be negatively affected by the modern world, and the Sentinelese don't need to concern themselves with sea level rise even if their island is completely swallowed.
I always wonder why these tribes haven't yet invented the iPhone? Obviously since they don't seem to need it.
For some reason you seem to expect a civilization with the technological sophistication of globalized society with 10,000+ years and billions of people and countless global resources fueling them to suddenly emerge in the small geographies and populations of uncontacted tribes? If you were trying to be witty, you came up short.
Edit: or were you trying to play off "negatively affected by the modern world" as, "well they don't have iPhones so they don't have the Social Dilemma, everything's peachy" instead of the blatantly obvious "we destroyed their world and they had no clue" angle...
