This logic checks out, however I do wonder if that’s actually how it happens in practice. As in, what percentage of their feed is grown somewhere that we absolutely can’t grow human food.
One good example is New Zealand. They only have about 2% of arable land and their population was always very small. Even when Europeans started to settle on the islands, overall population didn’t grow much. But once Europeans brought grazing animals, NZ population has exploded! Now the islands can support a lot more humans, plus they have enough excess they export to buy plant food they don’t grow.
Another example is Scotland. They have 10% of arable land and their population is less than 10% of total UK population. Yet they supply 55% of all beef in the UK and 63% of all lamb. And they still export some meat to EU even after Brexit, even though these exports have fallen drammatically. If you compare the satellite view of Scotland and England, you will see that Scotland is a lot more forests and wild areas, while England is just one large wheat and rape field with a bunch of large cities here and there.
Then there are Alps, which are known for high quality dairy products. Fuck all grows in the mountains so high (in terms of human edible food), yet there are many cows freely grazing and co-existing peacefully with the nature. Just like their wild ancestors did.
P.S. Fun fact - many public parks in UK cities have cattle proof entrances like the one you can see here in Cambridge. Because cows have no issues eating grass which grows in the parks, so you can use this land not only to enjoy your weekend or lunch break, but also to grow food. Here’s one in London. And not just in any random part of London, but it’s in Richmond, where old rich twats live.
And here’s a photo of my brother looking at cows in Richmond. Why pay to mow the grass and for cow feed when you can simply let them graze in a park? Win-win-win!
Please don’t present this as the norm for animal agriculture, as it’s disingenuous at best. The rare instances where this occurs are far outweighed by the habitable land use that animal agriculture accounts for globally. And even in the countries you call out, such as New Zealand, factory farming is on the rise, and pigs are almost exclusively factory farmed.
Calorie supply is irrelevant. The main source of calories today is sugar. People in developed countries like the US get 14% of their daily calorie intake from sugar, some countries like Brazil get over 20% from sugar. That’s way above the recommended 5%.
Another issue with your logic is that land used for grazing can and is simultaneously used for other needs, and it also supports natural bio diversity. Crop land is pretty much a dead land.
The chart also considers protein supply for this reason.
It’s extremely rare that grazing land is used for anything else. In fact, over half of tropical deforestation is done to create pasture land for cattle.
cattle eat somewhere north of 90% grazed material or so-called “crop seconds” which are parts of plants that people can’t or won’t eat. so, for cattle at least, it is true.
“Crop residues” or “crop seconds” only account for about a quarter of global animal feed, and the grain fed to cattle in the US alone could feed a billion people.
They eat plants we cannot eat in the areas we cannot plant any human edible plants.

according to the research on water use, hardly any grain goes to cattle first.
