I'm not posting this as a critique of the parent link, just as additional data about this topic.
Summary: In many Indonesian islands, there used to be large deposits of tin. Those have mostly been mined out, and sea floor mining has taken over. There are approved commercial companies that do it, but the video shows poor folks who are doing offshore seafloor mining "illegally" in very unsafe conditions. In either case, the practice rips up the sea bed and causes ecology problems.
* I quote "illegally" because the system largely sounds like it's powered by bribes to get the right certifications.
