people used to be able to book passage on freighters
still a thing though I think it costs more than it used to. Much like long distance train travel in the US, it takes so long that you end up paying more than the flight would have been (but it comes with lodging, meals and a unique experience)
with the amount of care and feeding that people demand as compared to cargo, and considering the gnarly fuels often used in ships, I wonder how much better it really is. of course it’s better pound for pound for shipping cargo, but when you add up all the amenities multiplied by the days/weeks spent aboard, I feel like it probably isn’t that great.
I’ve had the opposite experience tbqh. So far just about all the most principled communists I’ve met in real life are not vegan, some even a little bit hostile to the idea. I don’t know how to feel about that but it’s what happened. I thought there would be more. I guess I haven’t asked everyone, but it has come up with many of them
