Hey I'll take it a wee bit further to highlight INNOVATION.

After the great gulf culling and the social conversion of the coast into a wasteland there would be more than a few collapsed markets for foodstuffs. The price of oysters and fish skyrocket, causing underground aquaponics farms without any form of regulation to spring up everywhere. As each is found out as a source of salmonella or other toxin, as all corners are cut to ensure highest returns, the operators are forced to move quickly under new names to ensure that their customers never know about their past. Small arms combat between private contractors securing diy bioreactor feed for large scale aquaponics farms become more and more common as there are less and less foods, which only happens in food-poor neighborhoods. People living in rich neighborhoods complain about the parasites that want protection from the cartels that slowly establish more permanent gulf-food alternative farms need to pick themselves up by their bootstraps and shovel manure into the fish vats for 14 hours a day instead of 10. The poor are tasked with finding organic matter, paid by the pound, to throw in the feed vats. Those that couldn't afford the endless tests necessary to ensure factory grown crops by financiers with no concern for quality are safe die without burial money.
