That resource and logistics management problem is a direct result of people eating so much meat, the production of which is inherently inefficient for the purposes of feeding people. Of all the resources that we spend on maintaining and growing an animal, we only get back what goes into growing its muscles. The vast majority is wasted in maintaining the animal so that it doesn't shrivel up and die before slaughter. Scale back meat production and you get a lot more food for a lot less resources, energy and land. You can't get that efficiency otherwise. It's precisely about what we eat.

I'm almost impressed by how much completely unsubstantiated ad hominem you managed to cram in there. Personally I couldn't have guessed any of that from the comment you replied to. But if you wish to be taken seriously, maybe focus instead on the actual arguments next time.
