I would rather prepare by having food canned, frozen, dehydrated, or on the hoof and be able to live in the event of a diaster (economical, natural, etc.) than not prepare and be wrong. At least if I prepare, I have food. If I don't prepare, and something happens, I have had enough notice and only have myself to blame.
So, I am preparing! I will only need to protect what I have. I will not need to steal to survive. If I am wrong and nothing happens, I just have a nice food storage and enjoyed my garden and preserving. No harm done.
I believe that there are worse things than death. A slow starvation is one of them.
I have fruit trees planted. A garden growing and preparing food for long term storage. I have rabbits, pigs, chickens, quail, pheasants, and turkeys (on the hoof). I have water saved and continue to increase my supply. Goats are next on my list as well as artillery.
What are you doing? I would love to share ideas (not ideas about rather you believe something will happen or not) on what you are doing to prepare. Things like buying heirloom seeds so the seeds from your garden can be used to plant next year.
