I leave myself open to be corrected, but...
It is my understanding that before the current practices of animal farming with the changes in feed and methods of handling wastes, B12 was in the soils and it was not an issue.
Factory farming has done a lot of damage to our environment on many levels.
I have been doing this for a very long time. I eat mostly organic, non processed. I have never, ever had a shortage of B12 and only sporadically have supplemented.
I believe it is about balance. There are cultures (not here in US) that have primarily lived on a vegan diet and have no issues, but then they do not have the industrialization we do here, nor the factory farming.
I am sure someone will chime in and give you a better, more intellectual answer, but I wanted to get it started.
