In North America, we produce way more basic food than we can eat. Events overseas will not change that.

The problem is in the middle. Getting products into supermarkets in cities has glitches right now, with spiralling input and labour costs, and spiralling processing and transportation costs.

Personally, I grow a lot of food myself, and can expand that fivefold if needed. I also know half a dozen farmers. All around me they are growing wheat, potatoes, lentils, chickpeas, hogs, chickens, and cattle. I have the skills to process these foodstuffs myself if I need to. So, I'm not worried at all.
