I don't consider myself a prepper, but I am a survivalist. I grow at least 70% of the produce I consume, and I add to that yearly. I can, freeze, ferment or dehydrate enough that it lasts through winter until my next crop comes in. I buy meat in bulk (think buying half of a half a cow, a whole hog and so on) and can or freeze it. I can ready-to-eat meals. I can make yogurt, cheese, sour cream and butter from fresh cow's milk (I don't have my own cow yet but working on that) and I have chickens. I am working on turning the lawn in my back yard into an orchard, with fruit and nut trees, lining my garden with berry and fruit bushes. On top of this, I know which "weeds" are edible and which are poisonous. I can hunt for my own meat, and while it's not really my thing, I know I can survive if I ever have to. Now I have about 3 acres of land, but I grew more of our produce when we lived in Indiana and I only lived on 1/2 acre then. I think grass lawns, while pretty, are useless, and lawns can be turned into food if desired.
I do all of this, not because I fear the future shortages or anything like that. I do it because I want to be self sufficient. God provides for me through giving me the knowledge and strength to do all of this. I know exactly what I eat, no chemical preservatives I can't pronounce, I monitor and regulate the salt and sugar I consume, and I get a lot of exercise growing it. God provided me with everything I need to do this.
I donate bumper crops to a local church food bank, and I give a lot away to neighbors, friends and my kids. I have a goal of one day starting food tables at churches, that are covered for anonymity and weather protection. I want to offer seeds and directions on growing and producing food, as well as, how to harvest and store the seeds for future growing. Imagine the stress relief a single parent can have knowing they can grow a couple nutritious foods for their families, and never have to buy that food again. But right now, that is a dream.
