Thats an intersting article about acient agriculture. I'm not familiar with legends about Atlantis on this issue (can you suggest a reference about recent archaeological research on Atlantis?). In fact acient history is a great pool for ideas how to get back to a sustainable agriculture in our time. Another example is the biochar vision, that was also discovered through the observation of Amazonian dark earths from a vanished civilisation. Also permaculture is for me an old technique that we will have to catch up with again in order to preserve our planets resources.
