A holocaust is happening currently, 60 billion most docile and mostly female cows and fowls are eliminated every year. No one gives a damn.
Heck, even I don't. I drink my milk and eat my chicken. I consider those things mine and don't care if the milk is a product of forced selection that created a monster of a species, or that chicken is a flesh of an innocent animal.
I do not even care about what it does to the environment.
I'm voting with my money to have this practice continue.
The whole system is built for meat and milk to work. Yeah, it's some wierd suboptimal local minimum but that's what it is. I live in a meat culture and don't care if I can survive eating only plants.
