Before you answer: At some point, everything runs out. Your stored food has been eaten - whether it was a week, a month, a year...you could run out. Your "sustainable" food isn't sustainable; bad weather, contamination, over hunting/growing, migration, disease, etc. It becomes unsustainable at some point? Would you? I was thinking about this as I reflected on some relatives little fresh garden plot in the middle of Seattle. I'm sure they feel it's a great supply in case something goes wrong. I'm also sure there are some far less friendly people that will gladly remove them of the goods when the time comes. And then it struck me - for the unprepared, it will come in 3-7 days. For the minor preppers, a couple weeks or months. And for the rest, no matter what you do, it can happen. And at some point, likely would. I know we all frown up and loathe the concept of banditry. But when it is you/your kids or someone else's - would you / could you use force to survive when it all runs out?
