While animal wellfare is a thing, that's something else and if not a joke, appears to be advocacy for eugenism, something that will not help anything. It's like a type of revenge punishment against people who don't live the way they want, or an unrealistic pseudoscientific belief where humans would eventually become vegetarians via artificial selection.
It's noble to fight against unnecessary inhumane treatment and to improve farming and slaughter conditions (this reminds me that the political right is now retrograding the US on that front too recently). But there's been work by people like Temple Grandin who have helped to develop more humane conditions. Such and regulations are solutions, not the above nonsense.
Then there are interesting technologies that may allow tasty and equivalent alternatives, possibly viable, scalable and affordable, why not promote that instead of extremism?
