Additional Information
fisherman
several batteries of scooters or cars are still on the seafloor but I don't know how to salvage due to weight. I think they have been used as sinkers or anchors for a fishing structure.
Comments and Feedback
it feels hopeless, fisherman on the reef are the biggest polluters, and i seem to be the only person caring about this area, locals don't seem to care or understand of why i do this. I will keep doing
