  • Eggs shells don’t work unless they’re ground into a very fine powder.

    I don’t know the answer to this question. You may be right. And yea, I can see limestone in the right doses working.

    And we could always extract the nutrients from our waste. Close the cycle: what goes in, goes out. We’re already using biosolids in agriculture.




  • It’s more complex than this, but it’s related to climatic change.

    First, we’re still in the ice age. We’re just in an interglacial period.

    During the glaciation, humans mainly hunted a few big game. It was an inhospitable environment.

    When the glaciation ended, the climate became more stable, warmer, more clement. Rivers rised and became calmer, as the sea level rose.

    Humans started diversifying and broadening what they ate. They collected much more plants, hunted more animal species, notably small game, fished much more. It was the mesolithic.

    In zones that were particularly abundant in resources, probably at the edges of ecozones, it became possible and interesting to settle down somewhat, and defend this territory against outsiders. Owning resources allowed to invest time and labor into making things more productive. Domestication was part of that.

    Not all regions are suitable, or have sufficient domesticable species. Some places took much longer than others to really get farming going, and most never did, until domesticates arrived there from somewhere else.
