I regret butchering the paraphrasing in my previous reply to you, this is I believe the most powerful point (at least the most convincing to me personally) so I want to make sure it is clearly communicated as possible, quoting another ex-vegan:
> Start with Africa seven million years ago, because that’s where human life began. The climate, the creation of our ancestors—our beloved kin of bacteria, fungi, and plants—eased from wet to dry. The trees gave way to grasses and a tide of savannas rippled across the world. Cradled in the grasses were large herbivores. Twenty-five million years ago, in the exuberance of evolution, a few plants tried growing from their bases instead of their tips. Grazing would not kill these plants; quite the opposite. It would encourage them by stimulating root growth. All plants want nitrogen and predigested nutrients, and ruminants could provide those to the grasses as they grazed. This is why, unlike other plants, grasses contain no toxins or chemical repellents, no mechanical deterrents like thorns or spines to discourage animals. Grasses want to be grazed. It was grass that created cows; human “domestication” was, in comparison, just the tiniest tug on the bovine genome, and cows tugged back with the lactose tolerance gene.
Put another way, the grass depends on the cows as much as the cows depend on the grass. A symbiotic interdependence.
If the implied argument is to instead of eating animals that eat plants, to eat their plants directly, in the spirit of "refuting the central point" in Paul Graham's hierarchy, I responded in depth to @maxxxxx elsewhere in this thread who made the same point, but long story short humans cannot digest the grass which cows (naturally) eat. I definitely wouldn't advocate for grain-feeding, it is indefensible, but even grain-finished cows eat grass. Through the marvel of the rumen, indigestible (to us) cellulose is turned into delicious meat, milk, and (to grass) fertilizer.
Pastured grassfed beef does not depend on industrial agriculture/grain farming (corn, wheat, soy, etc.), and is in fact directly opposed to it. Instead of disrupting ecosystems by planting rows and rows of monocultures, grasslands of clover, millet, bluegrass, plantain timothy, sweet grass, fescue, etc. are sustainably nurtured by ruminants. Working with nature, instead of against it.
Cattle naturally eat grass, in a symbiotic relationship with the grasslands.
Joel Salatin, legendary proprietor of Polyface Farms, considers himself a "grass farmer". He maintains the grassland, which the cattle graze on and perform several important functions. Not only does grazing stimulate root growth, but the cow digests cellulose (or technically, the bacteria in her rumen ferment it) and emits fertilizer, feeding the plants ever hungry for more nitrogen and predigested nutrients. Grass uniquely grows from its base instead of its tips, so the cows eating and grazing on grass doesn't kill the plant, but rather the opposite.
Contrast with other plants with thorns or spines or chemical deterrents (such as coffee, caffeine originally a pesticide generated by the plant to deter predators, now cultivated by humans as a stimulant) or anti-nutrients or toxins. Grass has none of these. Lierre Keith explains in her usually floral prose how grasses want to be grazed, metaphorically: the grass created the cows (a similar point can be made about human domestication and lactose tolerance gene).
Of course, concentrated animal feed operations additionally feed cattle with grains. Grains are a recent invention on the evolutionary timescale: they didn't exist until humans domesticated annual grasses about 12,000 years ago, whereas the progenitors of the domestic cow, the aurochs, were around more than 2 million years ago. Cattle aren't adapted for grain, upsetting the delicate balance bacterial balance of their rumen, causing sickness. Poultry fed too much grain will develop fatty liver. So why do it?
Grains are cheap, very cheap. An ideal commodity, storable and portable. A dense organic form of energy, most likely converted from fossil fuel fertilizer thanks to Fritz Haber. And they cause explosive growth in animals, dramatically increasing both meat and milk production. The economic incentives are there.
That doesn't mean it is a good idea, or is sustainable or ecologically wise or nutritionally healthy.
Fortunately, grassfed grass-finished pastured beef is getting easier and easier to find. Thousands of years ago, used to be the only kind there was, now we are coming back full circle.
