This book briefly traces how the living systems emerged on the earth, created the biosphere and a cyclic energy regime of nature's economy over the geological time scale. Whereas in a short span of a few centuries, the productive industrial agricultural apparatus has depleted and exhausted the natural resources, compromised the quality of human food and marginalized the dominant human community, the small and marginal farmers. In the concluding chapters ways and means to reconceptualize agriculture to sort out its relationship with nature are highlighted.
