Arguing that "carnivores kill cattle but vegans kill field mice" is the wrong way to compare the two, as it draws a false moral/environmental equivalence. Monoculture crops are vastly more devastating than the "dead mice" argument suggests. To understand why, you need to grasp...
the concept of trophic cascades. Very roughly, living organisms occupy trophic levels, which means they eat the level below, and are eaten by the level above. The horror of monoculture is that it's an engineered trophic cascade, which means its aim is to destroy the entirety...
of the trophic level structure of a given ecosystem. The deaths of mice are only the visible manifestation. "Below" them, the death of insects, nematodes, and most importantly, soil microorganisms, are far more devastating. A healthy cubic inch of naturally maintained pasture...
has an astounding 900,000 microorganisms. Analysis of vegan vs. carnivore must take the destruction or preservation of this fundamental substratum of all life into account. This issue is complex because some kinds of ranching do harm this layer, and some kinds of organic...
farming take pains to preserve it. But generally speaking, a grass-fed, grass-finished, rotation-managed ranch that maintains diversity of 25-40 perennial grass and shrub species has vastly greater soil microbiological health and diversity. I would like this whole-systems view
to become the framework from which the seemingly endless vegan vs. carnivore (and variants on the spectrum between) debate proceeds. If the discussion isn't rooted in a sufficiently large framework, it wastes time at best and increasingly polarizes as worst. I am ready to be..
persuaded that someone, somewhere, has developed a vegan farming system that enhances trophic levels (or at least forestalls cascades) better than appropriate pasturing, but I have not seen that. And since I believe GF, GF meat is better for human health, I'll continue to eat it.
There's some good science in this thread, but the argument doesn't hold up at all. It's not veganism that's promoting monocultures, it's economics. Vegans are a tiny minority and would have no evidence of monoculture if sole reason. Yet we do. Which implies another cause.
Appreciate your point. I use vegans as convenient shorthand to describe the general economic trend that favors high-margin carbs over low-margin animal-based foods. Veganism has been seized by corporate interests, so it is a useful modern marker for an old, widespread trend.
This argument depends on a couple of things: assuming “appropriate” levels of pasturing- vast swathes of the American West have been desertified by overgrazing; and that cattle ranchers don’t kill what they consider nuisance species that compete for forage.
In California, I can see many examples of one side of a Valley with cattle and nothing but invasive grasses and maybe a couple of old oak trees, while on the other side- no cattle, lots of biodiversity, shrubs, trees, etc. No young trees or shrubs where the cows are.
