Big economic blocks like the EU and the US should force the cruise ships to operate sustainably and not pollute the literal sh*t out of the port cities they stop at.
"We should properly tax/negate negative externalities" in accordance with microeconomics. It's at the core of basic economics and both conservative and liberal economists would agree with this statement. It's a well studied field. The problem is policy. I often post this, but I really wish microeconomics was a required course in high school or primary. I find it to be one of the least understood of the well-established fields, and one that matters when we get older and vote or debate on these topics.
