For those of us who were around in the late 60's, early 70's, the Whole Earth Catalog was our 'bible' to self sufficiency. Between it and the tales of the great depression from our parents and grandparents it was a starting point whose time has come again.
Whole Earth has a website here if you want to take a look back at it.
From the Daily Survival comes a link to a ton of information on self sufficient living. Since there's a globalist plan to turn the U.S. into a third world country, some of the info may come in handy.
It's 13 gig of pamphlets, instructional manuals and how-to guides for the third world. A combination of resources by a whole alphabet soup of governments and NGOs like USAID and Peace Corps. You can find detailed, easy to read instructions for raising just about every kind of livestock and edible plant, how to build or make simple farming and building machines and how to build everything from houses to water rams to fish farms.
Your tax dollars probably paid for it, you might as well get some use out of it.
Organic Gardening is a long time source of gardening info and not to dissuade you from subscribing to the print edition but most of the information needed is available not only at their site but also throughout the net with simple searches.
Seedman.com is an excellent source of all kinds of seeds. It's even recommended by the local farmers co-op for some things that they don't carry.
And don't waste any kitchen scraps and organic material. Compost it. If you don't have room for a compost pile or just don't want to fool with it, there's always trench composting which can be utilized easily.
The main thing is to do a little planning, a little more learning and keep a little more change in our pocket instead of spending it on high priced organic produce or low quality factory farm foods. We'll always need that extra change for something else.
