I posted these thoughts on the main thread but it more appropriately goes here:
For those who are seriously worried about a breakdown in the food production/distribution chain and who are looking to home gardens, may I respectfully suggest that one think about prioritizing calorie-heavy staple foods.
Not saying don't grow tomatoes and peppers if you like 'em, but if our food supply is seriously disrupted, we're going to want our gardens to be full of squash, potatoes, turnips, cabbage, fresh greens. Chickens/eggs. Nut trees will be an especially valuable source of natural fat. Got local dairy? Local honey? Local pork? Who grows sugar cane near you?
