I believe that the data from developed nations has indicated that population growth follows a sigmoid and not an exponential. If that indication holds true for all nations as all nations become "developed", then population control is a naturally occurring phenomenon and the world will not have to resort to anything like a 1 child policy. If that holds true, then I believe the problem is far more constrained to climate engineering rather than social/societal engineering which may actually be possible. Hopefully it gets done in time!
