This paper attempts to integrate wildlife-related ecologic and economi
c variables into an econometric model. The model reveals empirical evi
dence of the presumed interdependence of human-wildlife and the holist
ic nature of humanity's relationship to the ecosystem. Human use of bi
ologic resources varies not only with income, education, and populatio
n, but also with sustainability of humankind's action relative to the
quality and quantity of the supporting ecological base.
