Truly ethical travel would produce little or no CO2 or other pollution. So unless you are already in Ireland, it is unethical to rent those high buck yurts. Society has gotten so used to fast, cheap transportation that they forget it is a major source of CO2.
We must go back to the days where you stayed closer to home and overseas voyages were done by sail. With gross overpopulation that exists, even the old way of using horses and other animals for transportation is too soil and water consuming, and the amount of waste produced would be another major problem.
