To continue food production there is one thing that also should be looked at for any form of long term disaster where self sustainability is a must for a longer period of time and resources are slow on delivering I am proposing that a publication be printed up showing individuals how to do pond culture. this can be done by stacking old timbers and lined with liners racks to be built so that they can harvest their grown fish and styrofoam panels be dropped in to use deep water plant growth. this can be accomplished using materials on hand from a catastrophy in rebuilding a reliable food source.recerculation pumps etc can be done naturally from pumps salvaged from other scrap appliances and put into either wind turbines etc. or use solar activated aireators
