Sir Albert Howard presents a summary of his life's work in this book. Howard states "This law is true for soil, plant, animal, and man: the health of these four is one connected chain. Any weakness or defect in the health of any earlier link in the chain is carried on to the next and succeeding links, until it reaches the last, namely, man." Howard's work, decades ahead of its time, provides an insight into how he realized the value of organic methods though he went to India intending to teach the use of chemical fertilizers and chemical pest control.
