There is no need “to reduce the growth of human populations”! Human populations are self-regulating and the current population rate decline is happening naturally, concurrent with the growing role of females in the paid workforce and within society. True, some patrioarchical regions are lagging behind, but it’s obvious that the societies that can harvest the creative and intellectual capacities of their female members will out-compete those that limit female participation. (Islamic and Latin American societies continue to struggling with one hand tie behind their backs.). With female participation comes declining fertility and population growth. Today we’re headed toward a more equatable equilibrium of the human population with the resources available (strongly resisted by the retrograde elites in power).
