just to connect another dot here:  industrial scale farms which are often completely petro-dependent, squander water on an epic scale, and are runnung a net-negative topsoil balance yearly.  in other words it is often a case of pitting a small relatively sustainable business against a corporate megamachine in the process of liquidation.  and the sustainable model will always lose in the short term.  then the industrial ag transnat will buy out the bankrupted small farmers and proceed to liquidate soil and water resources in their country as well...

meanwhile both the original hostile intrusion of factory ag products from industrial A into rural B in phase 1, and the ruthless extraction of soil and water resources in phase 2. will depend on fossil-intensive longhaul air and ship transport.

which of the eurotribbles is it who says, "when locusts move on they leave nothing behind"?

The difference between theory and practise in practise ...
