The only people who believe that animals cannot be raised as livestock in a sustainable fashion are the closed minded food, fanatics known as vegans.
It can be done, but not with your limited imagination and viewpoint on the world.
The problem is that people like you don’t want a solution. You want to be able to simultaneously claim victimhood while also lecturing and condescending to the entire world. Veganism is nothing more than an addiction to the sense of superiority over others.
If you actually cared about greenhouse gases, or animal cruelty, you’d be willing to explore other options. But vegans are extremists. It’s their way or no way.
I (and most people), on the other hand, care about greenhouse, gases, and animal, cruelty, and all of the other downsides to factory farming, but I’m not so stupid, I don’t have a big chunk of my brain, scooped out by religious fanaticism, so I can actually see alternatives.
The problem is, as you describe, poor resource and logistics management. Not what we actually eat. But you don’t care about that. You have a quasi, religious viewpoint, and you hate everyone who disagrees with you just because they disagree with you.
I’m sorry, you’re religious food fanaticism has blinded you to more rational options for dealing with greenhouse gases and animal cruelty. Your black-and-white approach is, clearly, not convincing me enough people to make a difference. So maybe you should focus on something that will make an actual difference: stop being a domineering, asshole, and lecturing people on how they should live their lives.
Nearly 8,000,000,000 humans require a lot of food. And it’s better that we eat livestock then depleting the local wildlife for nourishment. That’s a whole point of farming.
It’s still baffles me that anyone, especially in the last 10 or 15 years, suddenly thinks that this is a barbaric practice that must immediately end, despite the fact that this is the way it’s been for tens of thousands of years.
Because a bunch of pretentious, condescending jerks with some sort of food fanaticism should be able to bully everyone into their way of thinking.
It’s all about the seasoning
