There is an interesting connection of hypoxia (lack of oxygen) with humans illnesses when the author says that "the roots produced under hypoxic (soggy soil) conditions or under water are quite different from those produced in a quality container soil." Same is true for human cancers. It is now known that tumours are short of oxygen and the cells learn to survive in low oxygen- and they are different, just like those plant roots! What a similarity. And because of low oxygen content in the tumours, radiotherapy is not very effective.
