Breaks my heart to think at how greed motivates genocides.
I suppose the state of Brazil is something that could be considered a settler colonial project and with it's continued existence this sort of thing remains doomed to happen.
It happened on Brazil's watch so it's Brazil's responsibility, but I'm ill-convinced convinced that in its absence this wouldn't continue to happen (in its absence, there's no FINRA, no organization protecting these tribes... And there are still people willing to kill for mining profit).
