It's kind of asinine that one can be demonstrably stable over a long term and do all sorts of things operationally in the intelligence community, but could not even become a 92G (culinary specialist) in the Army.

To your first point about the small animals in the fields that are harmed by agriculture, I think that's worth having concern about overall, certainly. But many of the animals that people currently consume are fed large quantities of crops that incur that same cost. The average beef cattle is eating such things for 18 months prior to being slaughtered, breeding sows do the same for 3-5 years, and their offspring 5-6 months on average.

If there are advances in things like cultured meat that can be produced in a sort of industrial setting at a competitive price it might be possible to drastically limit both the conscious and inadvertent harm to animals.

Regardless, it goes without saying (from other, more well-sourced research) that the disparity of subsidies and government assistance provided to industries that ultimately exist to produce meat compared to industries that produce fruit/vegetables is fucking absurd.

Hard to consider this that sophisticated in the twenty-first century but their use of the number zero also predates Europe by hundreds of years.

The Palenque also contains both aqueducts and arches (though not used together in the Roman style): https://en.wikipedia.org/wiki/Palenque#Palace
