Pasture raised cows form a beautifully peaceful ecosystem, similar to what things looked like before humans. Similar for free range chickens etc. Modern agriculture and the factories producing vegan meat substitutes exist at a great cost to ecology and wildlife. Eat only what you produce on your homestead as a vegan and you will be sick - for no good reason other than your religious devotion and zealotry. Veganism is a daft, pointless, counterproductivre religion.
