If you read The UPT about page, there's a bit in there that cites how slaves weren't allowed to forage after they were freed from white plantation owners. Foraging is eating food that spontaneously grows in the wild (berries, roots, mangos, etc).
Gardening & sustaining one's self from the land has it own politics behind it. Yall see how over priced these plant shops be. Black people weren't allowed to have farms or churches or anything without racists burning their shit down.
Here's some extensive literature on food law gone wrong. Ancient laws that probably still exist that nobody knows about until you're standing before a judge who's in the mood to do some sentencing.
It's a 58 page paper, but I found it to be an easy read.
