Our state government has been claiming that Tasmania will become the food bowl of Australia, however if farmers can't afford to farm then where is the food going to come from?
Raising costs within the cities have caused people to shop without emotion. A mother with 5 mouths to feed will buy the cheapest they can regardless of whether it was grown in a factory or a paddock. That tends to go with produce, meat and pershiable items.
Something which also should be taken into consideration is that these animals don't seem to get along overly well. On a visit to a piggery (around 7 years ago) I asked the owner of the necessity of sow stalls. His reply was that he would rather not use them, however due to the cost he couldn't afford larger single pens and if he threw them all in together he wouldn't have much to sell later on as the pigs would attack each other. He did continue graphically what would happen but i'd rather not re-visit that.
