How Ecology Has Changed

Abstract

Eugene Odum adds new concepts to his previous literature on the ecological approach. Emergy, as an explanation of the quality of the type of energy, is discussed in terms of transferring to solar energy & species maturation. The P/R ratio, ecology as C.P Snow's third culture, & the two house conceptualization of the techno-ecosystem reward feedback are presented in terms of ecological interrelationships. The author concludes with the argument that modern civilization & nature is a parasite-host relationship, & advocates efforts to increase money & efforts to service our life-support systems by copying nature's reward feedback flow from our techno-systems by reconstructing economics in line with suggestions presented by Boulding or Hawken et al.
