Also wild ruminants cause similar, almost identical, CO2 emissions compared to pasture cattle. And if you’re re-wilding all those areas wild ruminants will be exactly who’s going to live on there, burping all that carbon plants sequestered right back up into the atmosphere.
There’s plenty of levers to pull when it comes to climate change, this isn’t one of it. On the contrary, it’s likely to be better to continue managing those ruminants because then we can feed them stuff that makes them burp straight CO2 instead of methane.
The actually big topics are transportation and heating, both should be (almost) completely electrified and electricity production switched to renewables (or nuclear, don’t wanna fight with you guys right now you’re free to pay more for your electricity if you want), and then further on industrial processes. Not doing things like waste heat capture nowadays is plain silly (though we need better district heating infrastructure to enable full penetration), chemical feedstock and things like steel smelting will require a proper supply of green hydrogen. “Muh there won’t be hydrogen cars” I don’t care. We still need the infrastructure.
The intensity of dairy and beef farming is magnitudes beyond what any natural population of cattle would look like. Also natural populations are in balance with each other. So if there would be more baby cows more predatory animal babys follow and eat them.
Your argumentation is started on a completely false premise and absurd.
citation. Things differ a bit depending on exactly what kind of environment you’re looking at but that’s still the rough ballpark. Yes, non-pasture farming looks different – but the area used to grow soy now would still sequester carbon, and it’d still be released back into the atmosphere by animals that eat it. Forests etc. aren’t bottomless CO2 sinks.

I don’t think you have a proper picture of what a natural ruminant population looks like. To give you a proper sense, Imagine a galloping Bison herd stretching, in a not exactly thin line, from horizon to horizon.
There’s green stuff to be eaten. As long as that’s there, the population of animals eating green stuff increases. Simple as that. It’s part of the natural CO2 cycle, to go ahead and say “let’s ‘fix’ the natural CO2 cycle so we don’t have to fix the man-made one” is ecologically naive.
A close to natural “population density” of cows is in the magnitudes of 1 cows per hectare of green land. Factory farms have hundreds of cows per hectare. So if the total population of cows would go down to 0-1% of todays farmed amount, that would reduce the GHG emission impact down to a negligible amount.
You are inventing a problem that doesn’t exist to justify the continuation of factory farming.
Surrounded by vast supporting fields which have none. Please, try to get a whole-picture view of anything before you post, don’t accost me with over-reductive narrow-focus BS, this is almost “The US has more people per capita” type of comical. Also, don’t just knee-jerk dismiss a link to a paper in Nature, of all journals.

No. And if you read the paper, you’d understand why.

I’m opposed to factory farming. For other reasons. Biodiversity, for one.
I read the paper you linked. Are you seriously suggesting that if we stopped animal agriculture, wild animals would flood the countryside to the same extent as in the Kenya study? I don’t think that is broached by the study at all.
A single study will not tell you everything about everything. No, ruminants will not just magically appear in the landscape, we’re living in a causal universe, after all.
Suppose, for the sake of argument, that all ruminants indeed all grazers (also deer, giraffes, whatever) are extinct. Plants will flourish, not being eaten by them, then individual plants, or parts of them (falling leaves etc) will die as part of their normal life/reproduction cycle – and get eaten by fungi, bacteria, etc. Which will burp CO2 and probably other greenhouse gases.
The condition for nature to produce CO2 are simple: The presence of carbon in a form that can be oxidised, such as sugar and starches of which plants produce plenty, the presence of oxygen, and a critter, any critter, that can do it. Even if it’s just a single species, it’s going to eat the whole thing and release all the carbon back into the atmosphere. Consuming available energy to reproduce itself is literally what life is all about.
If there’s energy around that can be used, nature will use it. Have a look at the most biodiverse and productive ecosystem in the world, the Amazon rain forest: It has very poor soil because as soon as something dies, its remains are recycled by something else. Destroying the Amazon rain forest releases CO2, again planting stuff there re-captures it, but reconstituted forest doesn’t continue to sequester carbon indefinitely: Only until it has accumulated the amount of carbon that it needs to sustain itself, after that it’s going to be carbon-neutral.
You may be asking “but then how did all that oil and coal end up in the soil”: Highly specific circumstances: Plants were producing stuff that critters couldn’t eat. But we’re currently not in that situation and in fact critters seem to be ludicrously efficient at evolving to break up new compounds. PET was first synthesised 1941, in 2016 scientists found critters which can eat it – producing CO2 in the process, of course. That’s exactly what’s going to happen to all that herbivore-free land you envision. If we want to sequester carbon, care has to be taken that nature won’t dig it up again.
