We also have a few wrecks intended for scuba diving.
Let's consider a vessel that has been abandoned or has sunk. You've probably dived around some vessels that weren't sunk for the purpose of encouraging dive tourism.
Is there a difference between vessels that were sunk appropriately and those that were simply abandoned? For example, maybe the fuel tank wasn't emptied before the vessel sank.
Is marine biodiversity the same around such wrecks?
