I've been reading books like, In Defense of Food by Michael Pollan, and Animal Vegetable Miracle by Barbara Kingsolver, and watching documentaries like Botany of Desire and Food Inc..
I gow a garden in the summer, and can as much food as possible for winter use. I raise chickens for eggs (if they'd start laying again), and I try to eat real food as much as possible, though we do still eat convenience foods more than I'd like.
I've been thinking more and more about living in a sustainable way, and the changes I would have to make are scary, but I think they're scary because we've grown up thinking that the way things are are the only way.
What do we do when we can't go to costco and buy a jumbo bag of frozen chicken breast? It sometimes feels easier to live in ignorance of where your food comes from, because once you've seen it, it's a lot harder to continue eating it.
I've joined the coupon craze, though mostly for non-food items since we don't eat a lot of the things there are coupons for (though I got a great deal on walnuts and butter and now have a nice supply in my freezer), but even for things like razors, I've had feelings of guilt for quite some time. I can get razors for free, but not the extra blades, so to never pay for razors we'd end up throwing away entire razors every time the blade goes dull. It's hard to balance the desire for a years supply of all things and still not be part of a rampant consumerism culture.
There are lots of things to think about, but in thinking about starting small, I'm researching how I can avoid eating commercialized meats. Being taught not to waste things, we'll finish up the bag of frozen chicken in the freezer over the next couple of months, and hopefully by then I'll have ideas on where to buy chicken that was raised in a sustainable way, that is healthy for me, for the farmers, and for the planet. I'll also look into the milk I buy and decide if I need to pay more for organic milk, and if that means that we'll be drinking less of it. And, if my chickens don't start laying again, I'll be looking into cruelty free eggs.
I know all of this sounds crazy to some people, but I feel strongly that we humans were placed on the earth to be wise stewards over all things, and I can't justify supporting companies that don't care if they're making us sick, or if their chicken farmers are developing allergies to antibiotics because of their overuse in the chickens, or workers on a killing floor who lose their fingernails to infections, or who care more about their bottom lines than about people dying from e coli poisoning.
I'm adding links to locally grown/sustainable farms as I find them. The one I have so far is Christiansen's Hog Heaven, which sells heritage breed pigs all processed and delivered in little packages. We're ordering a whole pork and splitting it among family.
