From a post at Crooked Timber on New Zealand [hat tip Marginal Revolution]:
Then you drive through a town like Edgecumbe, past something which looks for all the world like an oil refinery, and realise that it is in fact a dairy, the size of an oil refinery. Four million litres of milk go through that particular plant every day (one litre for every New Zealander), and it’s not even one of the top three Fonterra plants. A lot of the milk is converted into powder, which is sold to the Asian market. This was my first clue that I might be heading into some interesting economics – at the duty-free shop in Auckland Airport, one of the things that they pile up high next to the scent and booze is great big tubs of infant formula.From the context sounds like CAFO's have yet to come to the land of the hobbits.
Have I mentioned the David Hackett Fischer book: Fairness and Freedom, which compares the histories of the US and NZ. The post touches on the history of the white settlers with the native Maoris.
