Economic development lowers fertility rates (via various social/
behavioral and technological means). We are now living near the end
of an unusual time when we had technology lowering mortality, but
habits keeping fertility high. This caused the 'recent' population
explosion. Habits do catch up eventually. 1st world countries, as a
rule, are not growing in population organically (US population growth
is almost entirely a function of immigration), and a great many
countries have *declining* (and aging) populations.
Your fascist fantasies of forced popualtion control notwithstanding,
the world's population will stabilize entirely on its own.
