True that in the long term there will be much less being shipped around, but as long as we have people in cities in New York and Los Angeles and most of the food is grown in Iowa and Nebraska cornfields, the food needs to move around.

Once we hit the year of the Great Famine, when we have crop failures in say 2 of the main growing regions of the world like the midwest and SE Asia or Ukraine, all bets are off.  So many people will die in such a short period of time none of the big systems we have will survive, or be needed.  Same with a powerful pandemic (like Covid except 1000X worse).

However, as long as it remains a gradual shrinkage, we'll need to transition as much as possible from FFs to EV.  Far as shipping is concerned, those big container ships are ideal for powering with a nuke, we already do that with aircraft carriers.

Is it really plausible that we can build that many mini nuke reastors and mine up all the thorium salts needed to fuel them for powering the whole global transportation fleet land and sea?  Probably not, but we're supposed to not be negative and try to come up with solutions, right?  Not just throw up our hands and say we're mostly gonna die anyway and live like stone age H-Gs.  That's what I really think will happen, but I'm not supposed to say that because it's too Dr. McStinksion.
