But equally seriously over the last two decades or so a lot of the dormitory suburbs have been pushed onto really terrible soils, while a sort of "right to farm" regulation has informed Councils.

So it is not that easy. Supposing elite agribusiness grabs control of extended debt ridden farmers who have strived to become large, (high fuel costs will help), think "Soylent Green".

Except under the most benign conditions conditions there is more to growing vegetables than throwing in a few seeds and presto: Permaculture Paradise. Problems include really infertile badly structured soils, with bad water characteristics; and a host of pests, animal, insect, fungal and bacterial; which limits the crops which will grow, and causes really disappointing yields.

Thank heavens for Woolworths and Coles.
