There is an issue with the idea of pre industrial production. In ecoremediation we need to rewild large tracts of land to restore biodiversity. Most of this land is now used for farming and while a good portion of that land for half the crops in rotation goes to animal feed, it wouldn't be enough to simultaneously feed the population and rewild enough land if we stick to pre industrial methods. What we need is a clean, sustainable industry of agriculture. We are already on the fragile precipe of this new form. In the Netherlands we can find automated greenhouse operations that are increasingly becoming ecologically sane in their use of pesticides, fertilizers etc. They achieve an output almost double of traditional farming on a quarter of the space on method alone. In both the netherlands and singapore vertical farm projects are started to integrate city planning and farming, further reducing the need for space. In northern europe kelp farms are started to farm kelp and seaweed. There are probably many more examples but they are all post industrial practices which rely heavily on the scalability of industry. It really is the only way forward if we truly want to restore the plenty provided by a balance in nature. Restore the biodiversity, rewild the world, use less space.
