ABSTRACT
We are discovering how rich and unpolluted we need the soil, sea, and air around us to be, and how precise the supply of nutrients has to be, to generate and sustain healthy people. Soil-science, marine studies, and human nutrition discern the drastic effects on our basic physiology of our failure to respect soils, crops, and animals; oceans, rivers, and fish. Medical and nutritional studies reveal the effects of ill-advised farming and food processing and presentation.
