On the issue of exponential growth, in the case of human populations, see: Kates, Robert. 1996. "Population, Technology and the Human Environment: A Thread Through Time," Daedalus, http://www.csun.edu/~vasishth/Kates-Pop+Tech+Env.pdf
See also the literature on the Kuznets Curve. Exponential growth in human populations is an artifact of scale, it seems to me.
