That's great in theory, but there's just too many people for that to be anywhere close to realistic. If we had about 20% of our current global population, then I'd agree with you, but even the worst pandemic in modern history couldn't scratch 1%.
my parents grew up eating meat once a every few months, from animals they raised themselves. No big farm, just a house in a village. Is that not sustainable?
No it isnt because unless you eat/drink enough dairy or take B12 supplements, youre going to have a B12 deficiency if you do that. People forget that meat actually serves a nutritional purpose.
Well they did eat lots of cheese and dairy. Is that not okay?
You need cows to produce all of that just like you would meat. The way cow physiology works requires that calves be birthed periodically to maintain milk production at large scale. The dairy industry is to a large extent, a by product of the meat industry. Those new calves have to go somewhere. And you have to keep in mind that 70% of the world's population is lactose intolerant as adults. They rely on nondairy meat products for the majority of the B12 they get. OR you switch people to vegan substitutes that have B12 added to them. Right now those are niche/luxury products which is problematic for developing nations. Like... imagine going from small scale cattle and poultry farming to relying on B12 bacterial fermenters and soy production at large scale. That might be doable if new processes for using certain strains of B12 producing pseudomonas bacterial cultures can be developed for fermented soy products like tempeh can spread there but again, those arent there yet. More R&D is needed.
