I'm hoping this won't be a terribly unpopular post and I do hope I get plenty of opinions from both sides of the fence on this question. Why is it necessary to stock up on a year or two worth of food? Would it not be sufficent to have seeds and breeding livestock ready? I understand that different senarios could eliminate the practicallity of anything growing outdoors (nuclear or other type disaster), but I suppose in that case I would no longer be in a "mood" to worry anyway. Can somebody please give me a different viewpoint/senario as to why I may be unable to garden or tend livestock for more than 6-8 months (which would just be called winter here for the gardening) and therefore I would have to hold up inside my home for two years? And then what?
