You mean, the old style of farming where our agricultural output was sustained by unimaginable tons of ancient manures looted from South America?
We are already using ~all available animal dung as fertilizer; it provides something like 10% of our global fertilizer needs. We can't produce more animal dung than we are now; we already raise an absurd quantity of livestock, and we especially can't do it while also doing the other thing people suggest on this topic, cutting our meat production by 90%.
Gardening isn't farming. All crop farms of any scale use artificial fertilisers that wash off the land an poison our rivers and wetlands its not sustainable. Cutting out artificial fertilisers and gmo crops would cut our crop production by 60%.
We need to go back to our old style of farming before the world wars where we rotated between crops and animals and used the animals dung as fertiliser.
