Richard G. Walsh R.L. Johnson Kun H. John 1994 <p><span>This paper attempts to integrate wildlife-related ecologic and economic variables into an econometric model. The model reveals empirical evidence of the presumed interdependence of human-wildlife and the holistic nature of humanity's relationship to the ecosystem. Human use of biologic resources varies not only with income, education, and population, but also with sustainability of humankind's action relative to the quality and quantity of the supporting ecological base.</span></p> application/pdf 10.1016/0921-8009(94)90051-5 en Elsevier An integrated model of human-wildlife interdependence article
