Nothing says off-grid living, sustainability, and getting back to basics like foraging for your own food. While you may not be able to create an entire diet off of foraged foods, you’d be surprised with the amount of sustenance you can provide yourself with just by looking in your backyard.
When foraging its important to have a keen eye for what you’re collecting before you consume it. Many wild plants can look similar to others, and some are edible while others are not. We recommend Samuel Thayer’s book, The Forager’s Harvest. And whenever you’re in doubt, consult your local extension, and they can give you a definitive answer.
