post apoc media is always banging on about the necessity of macho survival skills but frankly it’s the gardeners/farmers who know 150 preservation techniques for winter beets and who understand the art of good pH balance in compost who will survive on our non energy dependent farms while you all butcher each other with katanas in burnt out shopping centres
The one thing that scares me the most about a possible apocalyptic scenario is food. See, at least in the US, most of our staple seeds (your corn/wheat/soybeans) are produced by Monsanto and that ilk. Now on the one hand, they’re bug resistant and high yielding, but on the other hand these companies aggressively go after anyone they think is using or reusing their patented seeds without paying. There used to be people that went around after harvest time and helped sift for seeds so the farmers could reuse and plant, but they’ve virtually been sued out of business. Your farm might not use Monsanto, but the farm next door might, and wind blows things around. Monsanto would rather sue and prevent you from reusing seed than take a chance on you planting and not paying them.
So, apocalypse stuff happens. a) Farms are more corporate operations these days, so are there even enough people to harvest the crops that are there? b) assuming a loss of infrastructure/gas etc it’s going to be damn hard to get crops to the cities, and you sure aren’t getting anything that we normally get from Mexico or overseas c) even if we make it through the first year, what happens in the second year, or the third?
