Efficiency doesn’t matter if you’re shipping material for production halfway round the world and shipping those products halfway back just because rich people wanted to outsource to cheap labour, and overproduce cheap crap that falls apart way too fast so they can sell us the same cheap crap again a couple years later. It’s mostly waste. Some shipping is necessary, but I’d say a vast majority we could do without.

Like I don’t believe for a second that these tarrifs will actually fix this problem because they’re just a big tantrum with zero strategy involved, but in an ideal world we would make a lot more locally and spend a lot less energy sending things all over the planet to make a handful of shareholders slightly higher margins.

I went looking and found this: https://en.m.wikipedia.org/wiki/Energy_efficiency_in_transport

And yep transport via boat is the most energy efficient.

That said I’m going to assume that OP in this thread is not talking about logistics efficiency, but rather a downturn in a demand for goods.
