First, is that by learning to identify, forage, and harvest our own food makes us self reliant in a way that not much else could.
Also, wild plants are typically more nutritional, with higher nutrients and minerals than conventional plants.
Getting out in nature is just plain good for us and has been scientifically proven to have significant health benefits, both for the body and mind. Foraging can also be good exercise if it involves any amount of walking.
Lastly, wildcrafting your own food and medicine connects us to nature more deeply and helps us to become attuned to the rhythms of the seasons, something that our ancestors likely understood very well, but we seem to have lost. Finding and preparing your own food helps us to reclaim some of that lost ancestral wisdom…how amazing is that!
I’m sure there are more, but those are what really stand out to me, and why I keep doing it!
