To "roam in the wild" conjures up vast area of natural forest converted
to farm land. Certainly these domesticated animals are not going to
survive in virgin territory for which they aren't even adapted? You mean
free range.
Like solar panels, wind farms and organic farming - you need A LOT OF
LAND.
No. I do not mean free range.
And yes, without human assistance, many would not survive.
Another thing to keep in mind that save the current generation, the population of new generations would decrease substantially if breeding practices stopped.
