Give me a break with this sanctimonious drivel. Ship owners don't drive around the oceans aimlessly for fun. They are facilitating global trade. The computer you wrote your post on was probably delivered via cargo ship. Ditto half the stuff in your life that you obviously take for granted. So I hate to break this to you, but you are just as responsible for "polluting the atmosphere" and "damaging the climate" as the ship owner, because without you that ship has no need to sail.
Please let me know how you plan on reimbursing me. I accept Paypal.
Granted that we have collective responsibility for human activity, then only by collective action can we assume stewardship of our responsibilities. The basis of collective action is first consensus, which is achieved through communication. Therefore the grandparent is taking a perfectly rational action in communicating their distaste for the system.
I feel second-hand embarrassment for your combative and flimsy dismissal.
The failure of economics, that you should look at is in the price of oil. The are polluting the atmosphere and damaging the climate and not reimbursing anyone for the damage they are causing.
