I disagree with your premise.

Historically (more than 150 years ago) almost everything of value came off of land.  As recently as the early 1900's many products were made from plants.  Pigments, paints, fibers, insulators, structural material, and on and on.  Furniture, dwellings, fabric are all made from plants even today.  Farmers grow more than just food and always have.  The problem is that oil has forced farmers to grow almost exclusively food because oil products substitute for everything they used to grow.  And I haven't even started on the animal products that are used for non food uses.  Oil makes many of these pure waste products, rather than the added value products of my Grandfathers day.

NC,,,it was termed Food and Fiber. Older books by the USDA spoke of it that way. Food and Fiber.

I remember well the sheep we used to shear on the farm. The geese for feathers. Hemp needs to make a comeback.

I think if this country survives the meltdown then it has to come back else we won't have anymore plastic clothes.

I always did prefer cotton and wool. Let the wimmen go back to the ironing board and forget 'permament press'. Obligatory smiley and several LOL's so I don't get lambasted. Only kidding wimmen, only kidding!

there were less people back then too.. billions less.
reduce the population enough and we can once again do the same but of course the required die-off is not what you want if you want to go back to that.
