A question interesting to me: Are cruise ships worse or better than package, tour or individual holidays? We have millions of people all over the world who want to travel and see the world and enjoy themselves. Assuming we don't ban individual travel we probably want to work out the most environmentally friendly (and socially responsible) way of enabling this. A network of railway lines across the northern hemisphere connecting to a fleet of wind powered cruise ships? But paying staff a socially responsible wage might push the cost of a holiday up above the once a year point. And figuring in the real environmental cost would cause issues as well.
