Dehesa is a great example
Pre industrial was all permaculture, you don't need to feed the whole world and even with 'enough' food we don't/aren't. Localised food excess traded was the model, it's how the picts and celts had salt from German mines and how Egyptian beads were found in Cornwall, those people weren't all eating the same thing, they fed themselves and traded excess. In the UK the spread of oaks coincided with people because we fed our pigs on acorns and made acorn flour, it's not mad to suggest they ate a variation of bacon sarnies at stone henge. Yes healthcare and life expectancy was low but in terms of production I'd argue we were richer

What do people think happened before the industrial revolution? Do we all believe it was like modern survival shows like alone or naked and afraid? Course not, people curated their resources and grew them to abundance or followed migrating animals, herds, fish, again managing them to abundance. The rainforest is permaculture,

the dehesa and Chinampas and most areas of our planet were farmed in a nature positive way else they faced malthusean collapse.
Nearly all the world Ills can be attributed to this seperation from nature, sexism and rasism tie in too.
the regional fishermen are going exstinct with the regional fish. The common human has been seperated largly from benifitting from their labour or owning their resources.

Monoculture makes us all poorer, unless the idea of life seperated into a series of tower blocks excites you, one block for verticle farming, another for people, one for pigs, oh and rip up the deep seabed for solar panels to power it. Sigh. When it all comes a crashing down those smallholdings that 'can't' feed the world will soon get bigger. At the moment the economic structure doesn't like small scale, it's get big or get out and human wages essential to permaculture which employs farm more people hobble what should be profitable permaculture farms. Driverless tractors anyone? Monoculture often cuts people out too, forcing us into urbanisation

As mentioned above localised people protect their land which is large scale permaculture. Ever heard of gaia theory? James lovelock started out working for nasa trying to find signs of life, that led him to our own very much alive planet
