@mikebrunt interesting stuff. But also has the potential to be quackery. I'd like to find some independent review of these ideas.
@mikebrunt If this paper is any indication, it sounds like other scholars are taking the ideas seriously, but at least the full scope of what he presented isn't considered fact at this point, and there are other theories.
@acjay Yes and understood. I spend a good deal of my life working on permaculture projects so the implications of this interest me. I am reading a piece by Richard Feynman at present about this. https://www.feynmanlectures.caltech.edu/II_09.html
