The twin research study was. Two were about land use.
The last one was simply a list of related research, to show how and where opinions vary even among researchers. I tried to keep it politically neutral. The links posted does not tell you what to eat, or how to live your life.
Half of the world's habitable land is used for agriculture, with most of this used to raise livestock for dairy and meat.
This is not true. The base of this arguments, as I said before, is the false idea that we grow crops specifically for animals.
The most common food for dairy cows is grass. Canadian dairy farmers work closely with nutritionists to find diets that work best for their specific cows.

The comparisons between corn usage in human food, cattle feed and diesel.

Results estimate that livestock consume 6 billion tonnes of feed (dry matter) annually – including one third of global cereal production – of which 86% is made of materials that are currently not eaten by humans. In addition, soybean cakes, which production can be considered as main driver or land-use, represent 4% of the global livestock feed intake.
While livestock is estimated to use 2.5 billion ha of land, modest improvements in feed use efficiency can reduce further expansion.
57% of the land used is not suited for land production.
Think of terrain too uneven, or soil unusable for crop, Observe rural farmlands: you'll see flat land being used for crops, and hilly land used to raise livestock.
Producing 1 kg of boneless meat requires an average of 2.8 kg human-edible feed in ruminant systems and 3.2 kg in monogastric systems.
HOWEVER, only a 13% of the total animal feed is theoretically edible... it consists of very low quality grains, which make up a third of global
cereal (not total crop) production. Stuff still too deficient compared to the commercial harvest to seriously consider taking it.
The alternative to not feed animals is to waste a huge amount of leftovers we can't do anything with.
Acres of crops fail every year. Those are meant for human consumption, but ends up as animal feed. Manure is a very good fertilizer, but vegan defenders don't seem to mention crop failure and the fact animals can recycle that. In a began world crop failures mean no vegan food. However, the reality is that crop failures are feed for ruminants which is nutritive to them and make good fertilizer to regenerate soil.
The majority of animal feed is from farming byproducts that are inedible to us: pulp, failed crops, inedible parts of plants and not just their grain, soybean hulls, wheat germ, etc. All the leftover crop parts that are to be sold for human consumption: what we can't eat.
Plant-based diets produce this leftover we can't do anything with. Without animals, those would still exist because
we don't eat the whole plants. Hence feeding those to animals in exchange of their fertilizer is highly productive.
Why a farmer with land to grow anything profitable would choose to grow anything but that what yields the most profit?
Feeding the soil with vegetal compost takes too much. Lots of space, absolutely massive amounts of organic material, and then doing it right and not just letting things rot. At a large scale, it would be a logistical nightmare and the work needed makes costs way too high.
You like to underlook farmers, but they are professionals. They don't do that because tradition, but because it's the only way we could've continued. Think of a large civilization that survived thousands of years without animals: exactly, there are none.
The logical conclusion of your study is that farmers are dumb enough to grow crops they don't need solely to operate at an economic loss.
The Food and Agriculture Organization of the United Nations (FAO) recognizes the value of animals and don't recommend veganism at all.
It's safe to assume with all of this that veganism is inapplicable to the real world.
This is without counting the health issues.
- Vegan diets are devoid of many nutrients and generally require more supplements than just B12. Some of them (Vitamin K2, EPA/DHA, Vitamin A) can only be obtained because they are converted from other sources, which is inefficient, limited or poor for a large part of the population. EPA+DHA from animal products have an anti-inflammatory effect, but converting it from ALA (plant sourced) does not seem to work the same. Taurine is essential for many people with special needs, while Creatine supplementation improves memory only in those who don't eat meat.
- Restrictive dieting has psychological consequences including aggressive behavior, negative emotionality, loss of libido, concentration difficulties, higher anxiety measures and reduced self-esteem. There is an extremely strong link between meat abstention and mental disorders. While it's unknown what causes what, the vegan diet is low in or devoid of several important brain nutrients.
- A vegan diet alone fulfills the diagnostic criteria of an eating disorder.
From the first link I posted.
You underlooked the serious health concerns under the excuse of "it's too unlikely" and moving the goalposts every time I counter-argued: first it was that my interpretation was wrong and the real number of affected people was lower: when it was proven false, it went to underlook the numbers I posted as if they weren't a big deal or had risks in other areas. You said the problems are "tricky": not they aren't, they are a huge problem and statistically unavoidable.
Veganism is an unhealthy, unviable, and useless ideology that:
- Possesses risks not present with balancing animal food, regardless of the quantity,
- Cannot be applied due to the unviability of using solely vegetal fertilizer,
- Animals will always exist because it's extremely profitable to use them in crop growth,
- There isn't enough fertile land to renounce animal meat.

If you really want to renounce animals, you'd need more land to fertilize stuff. And I don't know if you're aware, but huge numbers of moles, small mammals, reptiles and insects are killed first to prepare the land, and then in traps and pesticides so it can grow. Do you seriously realize how many animals die in the process of growing crops?
I'm one of those! I'm not going to argue against the occasional culling of a sick population, but I do argue that the overall balance is a rollercoaster started by human, which ought to largely be left alone. It's driven by greed and human needs, with
some but way too little concern for other species.
I think Chernobyl demonstrates the effects of just leaving nature to find its own balance. Even with high radiation levels, the animal populations have thrived. The wolf population recovered particularly impressively.
(I'm worried about the long term effects, but it still say a lot about the supposed importance of killing wild animals.)
How Chernobyl has become an unexpected haven for wildlife
A "haven" lmao.
It's literally common knowledge than animals don't have pleasant lives or deaths in nature and most are stuck in constant fight or flight. At least we give them humane deaths, hunters are trained in where to shoot to minimize suffering instead of your model, where animals starve, disease, and get regularly tore up into shreds alive and aware of everything.
There is no welfare in nature. There can't be welfare without human intervention.
