This is a very silly take. If you consume any animal foods raised in the US, you are consuming canola / rapeseed meal, soybeans (90% of soy grown in the us is used to create animal feed), and sunflower seed / meal already. You are consuming it in a condensed secondary form (one tropic level up). It seems exceptionally backwards to be worried about eating any of these foods when the animals you eat are essentially just condensed versions of these ingredients where any downside effects would have accumulated heavily.
Also canola oil is now considered on par or healthier than olive oil. Soybeans are one of the worlds few complete plant protein sources with a high quality protein and widely consumed all over the world to both animals and humans to much beneficial effect. Sunflower oil is the least healthy thing here, but still considered quite healthy without excessive heating.
This is a bad take. Of course methods meant for a local region don’t scale everywhere. Different regions require different methods of cultivation, and should be applied in the correct places.
Ideas like syntropic / successional agroforestry are needed to scale a place from having bad soil, to slowly accumulating nutrient density, and accumulate soil health. This then supports a successional planting of trees with an end goal of a mature forest with multiple healthy stories and a healthy loam underneath.
This doesn’t mean you need large herds of free animals (though obviously if you build these forests, you will accumulate more animal biodiversity since they can thrive there), but free roaming animals certainly can help in some circumstances. Though large herds of bipedal monkeys will definitely be needed.
