“…In proposing this system of 14 energy-and-production chains and their aggregates, I stressed the feedback effect of these process chains on the natural environment without really demonstrating the cyclical character in the system of interactions "nature-production-man-nature." I. V. Komar suggested that the various forms of interaction between processes be investigated for the cycle "nature-society-nature" together with the impact of human activity on the natural environment [16,17,18]. Komar mentions a distinctive "social link in the overall terrestrial circulation of natural matter that is distinguished by qualitatively different laws of operation and development" [18, p. 72].…”
