As negotiations get underway at COP28, we compiled a list of the leading research documenting the connection between meat and greenhouse gas emissions.
My one rule on this topic is never getting into a gishgallop. Vegan advocates love to play the roulette of swapping topics every time they lose ground on one, until they manage to win the argument having lost every piece of it by just tiring the other side out. You pick one of those topics, and I will field that topic only with you. It might surprise you, I will agree with you on some of them (like saving the Amazon).
But if you make me choose, I will choose land use because it’s a slam-dunk. 2/3 of agriculture uses marginal land that cannot (and I believe should not) be made arable. If resources were spent changing that instead of vegans fighting with farmers, that number could approach 100%. There’s important asterisks about that (both crops and livestock become more environmentally friendly if done close to each other due to their symbiotic relationship) that need to be kept up. But reducing livestock population directly WRT marginal land is wasteful.
If you want to discuss this you’re going to have to get more specific. What agriculture, where in the world, are feedlots used etc You’re obviously excluding aquaculture, and non grazing animals like pigs, I suspect you’re also excluding egg production since that is almost monolithically cage farming.
Like you can’t really say “oh these pigs are on non arable land” if that merely refers to their physical location and not where their food is grown.
So could you please drill down a bit? what specifically are you referencing?
If you want to discuss this you’re going to have to get more specific
Which part of this? Marginal land? That’s a very specific topic. Why should we bring in 100 different variables unless you can show those variables matter to marginal land.
Or are you sayign there’s some prima facie point I’m missing where “nothing but wild animals on marginal land” will produce more sustainable food than “cattle on marginal land”?
Or are you just trying to get me to provide enough information to overspecialize my rebuttal so that your side need only say “ok, everything but that”?
I just need to know where you’re pulling that from and how it was calculated. Otherwise we’re just going “tis!” “tisn’t!” till one of us gets bored.
Like are you referring to cattle farming in Botswana? global stats? all animal ag including fishing in Japan?
I can’t discuss a magic number, I have to know how it was derived and under what assumptions. Then we can examine the assumptions and methods of derivation and determine whether or not we agree it to be true and why or why not.
My argument on marginal land is prima facie so far. I picked it because it seems obviously true on the surface, so I can let you provide your points to try to blow it up. I’m referring to the land use problem, which is the often-cited vegan argument that livestock land could be instead used as forests or croplands to sequester carbon.
If you want to contest the 2/3 marginal land number, I’ll cite a few references, but it seems an odd number to consider “magic”
A magic number is just slang for a number which has no obvious reason for its value.
I literally can’t discuss this because I have no idea what it’s saying. It seems obviously false to me when we factor in the land used for their food production. In the heaviest meat eating/producing countries only a minority of calories produced are from pastured animals. Most cattle are from factory farms involving feed lots, pigs/chickens/fish are fed crops grown on arable land.
Like ~75% of the world’s soy is grown for animal feed https://ourworldindata.org/soy and soy is a massive crop so it’s hard to imagine where all this saved land comes from. What are you comparing against?

Which number is a magic number to you? I thought I was clear in asking that question.
It seems obviously false to me when we factor in the land used for their food production
I’m not sure what you’re saying here. Cattle and most livestock can graze on marginal land. What land would be used for food production? Here’s the land-use breakdown.
That’s not an accurate statement to the reference. 75% of soy crop is fed to animals. That’s a very different reality. It still jives with the 86% of feed that is human inedible. How? Because a high percent of the soybean crop is inedible to humans, and there’s been a huge influx (your link agrees) in demand for soy products in general. That soy waste a cheap option for feed. The alternative is burning… but we cannot continue down this line without dropping the land use topic. 100% of the marginal use livestock diet COULD come from the marginal land. If we didn’t need to get rid of this other stuff anyway.
I feel like you’re doing the thing you premptively accused me of wanting to do.
You’ve put forward an arbitrary unsourced number asserting that 2/3 of the land used for animal agriculture is otherwise useless for food production, with the implication that we would need to use more high quality land to meet human food needs. Thus losing out on any benefits we might get from freeing up this marginal land.
That number is undiscussable until you can actually demonstrate to me how you’re arriving at it. We can’t have a discussion if you’re asking me to work out the specifics of your claim and then disprove them, you have to actually make a specific claim.
Getting into the weeds on the details of soy and hashing over the whole by/co product and economics of various crops with and without animal ag is pointless until we know what it is you’re actually claiming.
So please, make that claim. If it is trivial to prove that animal ag uses less land than plant agriculture then do so.
>It seems obviously false to me when we factor in the land used for their food production
it **seems** obvious, but we feed them cottonseed, which is a byproduct of the textile industry. why should the land and water and emissions spent to make tee-shirts and jeans also be attributed to cattle? we feed them silage that is byproduct from other sectors of the ag industry. we feed them soy cake, a byproduct of soybean oil pressing.
these are conservations of resources. why should we say it costs those values rather than saves them?
Ok I’ll humour you: what are vegans wrong about?
Land usage?
water usage?
Fertiliser usage?
That animal farms are hubs of disease outbreaks?
Thermodynamics?
Where the Amazon is going?
That killing/branding/doing surgery/forced impregnation etc when you don’t have to is wrong?

https://ourworldindata.org/soy
this link is great because they include this graph
it shows that about 69% of the soybean crop ends up as soycake. that is the byproduct of oil production.
>75% of soy crop is fed to animals.
85% of the global soy crop is pressed for oil. the vast majority of soy fed to livestock is a byproduct of that process
