Yeah, the issue is livestock eat crops to energise themselves, so livestock inheritly requires exponentially more fertiliser than just the crops would.
ruminants eat grass, which humans cannot eat, and turn it into protein, which humans can eat… grass grows on land that humans can’t use to grow crops… and even crops humans do grow cannot be fully eaten by humans, something like 70% of the biomass from cropland is not consumable by humans… which we turn into human food by feeding to to animals that can eat it.
you will see they are already farming everywhere they can farm…
it wouldn’t be “efficient” to ignore 88% of your productive land… and even if you do ignore it, the sun still shines on it, the grass still grows on it… something is going to eat that grass, even if it’s just bacteria… so the ecology is going to keep marching forward no matter what, that is why its a biocycle
how do you not understand that the more meat we consume, the more the crops that need to be grown? the vast majority of farmed animal meat is grown with far more crops than it would ever take to just feed people the plants. its incredibly simple arithmetic.
Most crop biomass is not edible by humans, so that 70% of biomass we can’t eat is fed to animals. That doesn’t mean the crops are grown exclusively for animals, it’s just an industrial efficiency
It seems like you were not able to look at the map, 88% of the food producing land of Australia is only suitable for grazing animals, to make meat
I guess there are no consequences to flooding a land with non-native cows or sheep or whatever and letting them eat everything in sight. Or even just artificially increasing the native population of your choice to do the same.
Have you not heard about the tons of fertilisers needed for crops?

30% is still quite a lot (much more than just eating a plant!), and the land still has uses beyond just farmland.

Unfortunately, simple and true are often at odds

If you start with the premiss that humans need to live and be healthy - and work backwards from there, you end up with ruminants and land conservation
You could use the same argument to throw a datacenter there, but just because nature is undistributed doesn’t mean we need to disturb it.
Efficiency also includes space efficiency, as we have destroyed more habitats in the past hundred years than some extinction events.
what do you think people feed cows?
thats right, its crops
GRASS, I know you know it’s grass because you responded to the comment with the grazable pastoral GRASS LAND map.
