Still in my point of view it's immoral to kill. All the land used for animal feed could be used to produce plant-based food... And yes, I totally agree: one or two cows at the farm lives a happy life, gives maybe birth to a baby cow, will give 90% of the milk to her baby, which will not be taken away from her and 10% goes to the farm-family. This is balance and I would say moral. Same with chickens etc. But this is sadly not the norm anymore. And yes, I also agree, that monoculture is not good at all. But the food fed to cattle is mostly produces in a mono-cultural way...We got to find a balance again

You're very passionate about this, which is certainly respectable. But, I would never refer to killing as immoral per se. I don't think that term fits the context of your statement properly. Keep in mind that maintaining a plant-based diet can have many serious negative consequences, such as a high calorie intake with very little protein, which could lead to overeating and bloating. There's also the possibility of developing unhealthy eating and sleeping patterns, experiencing a lack of ₿ vitamins and iron, high sugar intake, reduced production of essential digestive enzymes, and digestive issues that can arise. I think It would be a good idea to prioritize your physical health over your subjective beliefs on dieting. Perhaps, you should reexamine your outlook on being vegan. Honestly, veganism never seemed reasonable to me. My two cents.
