” 8000 passengers?”
Think of the amount of sewage that thing will dump once offshore.
I am imaging a trail of belly-up fish following it out to sea.
They have better sewage treatment than almost any city. And they dump NONE of it.
You know NOTHING about that.
Bet it doesn’t. The boats have very green credentials. Waste recycling is pretty much required for a non military vessel. They only dump grey water in the ocean. Solid human waste is dried out and compacted.
