Paul R. Ehrlich was the author of the 1968 book "The Population Bomb" which forecast dire circumstances for human civilization due to overpopulation (which turned out to be overstated).
He encouraged population control to reduce the incidence of famine and disease.
The "Ehrlich equation" is a simplified comparison of the factors for population sustainability.
I = PAT where
I = the overall Impact on the environment and Natural Resources (which has a finite limit)
P = the total population
A = Affluence, or the average quality of life
T = Technology, or the increase of Impact by intensive technological efforts to utilize resources.
