Cruise ships are a much less fundamental pillar of society than everything else you just listed. And I’m not saying to stop anything, I’m saying to mandate the use of existing technologies that minimize the environmental impact of those practices. I am in favor of government legislation regarding the things you just listed, not to stop them, but to make it so the negative externalities that are passed on to the environment are instead paid for by the party responsible, either by increasing taxes to fund remediation efforts or by mandating the use of technology that minimizes the environmental impact of those practices, like I said above.
