The paper proposes an analysis of the relations between economic growth, population growth and natural ecosystem carrying capacity, applying an ecological economics approach. Starting from construction of a standard economic growth model, we introduce the effect of a natural renewable resource. The aim of the paper is to analyse the sustainable growth conditions emerging from the linear interaction model of the two populations. Connection between the biological and economic aspects of the model is achieved by integrating the concept of carrying capacity for the human population with that of subsistence, a concept of classical economics perfectly consistent with Malthusian demographic analysis.
