This is often quoted and misleading. It doesn’t emit a million times more pollution than a car across the board, it emits a million times more sulphur oxide than a car.

Now sulphur oxide is nasty stuff, and regulated out of vehicle emissions for good reason. Fuel conditioning and catalytic convertors take care of this. But those things add cost, and why would a cruise ship company do it if they are not compelled legally and their customers don’t mind?

I don’t feel bad for giving my friends who go on cruises a hard time over this. Most will say they simply do not care about the environment. They are not immediately threatening their own immediate habitat. These are the people who go on cruises. The fact that the cruise industry exists is a sad mark on humanity.

Not only sulphur oxides, particulates as well (see my first quoted link). Particulate matter from combustion is extremely nasty. These floating petri dishes choke everything in their path.

Because their owners give a shit about the world they're leaving to their children?

Oh, well, I suppose they don't, then, do they?
