1. My food does not, why does yours

2. There are many alternatives to fossil diesel

3. The alternatives involved decentralised technology, so is actively opposed by entrenched interests who would burn the world for a dollar

The solution to that would be "locavore":

Electric trains can ship overland cheaper than diesel trucks. If we'd put half the money we put into free/subsidised highways into rail instead, the problem would already be solved.

The last mile could be fairly easily electrified at this point, battery trucks are quite sensible for short distances.

is that a serious quest?

outside of the US most trains try to run electric when they can as it's just plain better (cheaper, more convenient too). Yes bunch of fright trains still run diesel, but that is mostly due to historic reasons and them often going to niche side tracks which have not been electrified. Fun fact a supper heavy mining fright train in Austrailia doesn't just run electric but basically 0-cost. It gets loaded in the mountains uses mostly gravity to run to the sea charging batteries while breaking and then when empty goes back up using the charges gained from breaking.

And electric trucks exist and work, too.

You don't even need latest battery tech as e.g. Swiss/Zürich hybrid bus/trams have been showing since some decades.

As another fun fact Beelitz-Heilstätten only allowed electric car around 1900!! (because it was healing lung issues and even way over 100 years ago it was well understood that air pollution from cars makes that worse).

Like, this was never about weather it's technical doable. But all about gigantic well established industries doing everything in their power to sabotage forced changes as such changes would make them obsolete. So a technical working solution isn't sufficient it must be noticeable cheaper or better so that it can disrupt the industry in a more "capitalist" way.
