Because you cannot have 1000 cows on a grass based system, I think all intensive farming is wrong. It is unatural for 1000 cows to be in buildings all the time. I had a brother who worked in an intensive dairy farm and they had supacows, which literally gave milk for over a year ,or more, only on one calving, also they gave them a specific mixed ration and if anyone messed it up slightly they could become seriously ill. The reason why I hate intensive farming is because they treat them like machines and not like animals.
