If we all moved to impossible beef, cattle populations would plummet. However, despite popular perception, for most of its life before slaughter, a cow is raised in large open ranges for grazing, like in the California foothills. Only the last parts of their live do they get put into crowded feedlots for "fattening", which might be described as inhumane. Perhaps, it would lead to the advent of wild cattle in the California hills, as land owners stop caring.
