The polluting the waters they go bit is one of my only concerns to push back against. Depends on the ship but they shouldn’t be actively polluting the water and when they do it is a mistake or the annoyance of lack of laws letting someone be lazy.
Food waste is sterilized and neutralized to be be able to either dump into the ocean if it can or be disposed of later. All trash is sorted and recycled or burned for fuel with scrubbers removing heavy pollutants from the smoke stack.
Quite a few ships actually get unprocessed gas as the processing generates the lubricant they need for the engines and allows for less chemical release at the site of the processing. And is offloaded once spent to chemical handling companies.
They even purify their own water before dumping it using algae and enzymes before uv sterilizing it.
They just mess shit up in ways that are also hard to explain, such as oasis class ships were so large that then traveling to Venice had an issue where the vibrations of the motors were shaking the foundation of the city and causing parts to collapse. Their wake churns algae from water oxygenation and so much more. But they are more or less just a city on the water with all the ups and downs of a regular one with more classism.

There are a lot of things they’re supposed to do that they don’t.
FoE has “report cards” on the major companies and they’re all awful.
It’s more the air that they pollute. The NOx and CO2 emissions are absurd.
