This post is awesome! When I used to live with my Matriarch, Sundays were gardening day and we grew our own vegetables from leafy greens from the Camote plant to eggplants, okras and, squash.
My matriarch had a green thumb and could pretty much raise any kinds of vegetation.

I live in an apartment with no room to plant but agree with you on how our current food system is not feasible in the long run. I still like eating meat though so its hard for me to swear off cattle and hog farm.
