I am not disagreeing with you about population modeling. Altho I don’t have the numbers with me right now, from my earlier calculations, it would be 150 years to stabilize world population at the carrying capacity of one billion. But I think it’s better to have half a surviving child per person(rather than one child per woman. we don’t have the time to deal with the definition of ‘woman’)for the sake of genetic diversity. And this right to procreate should be non-transferable. (No one can buy or sell the right to procreate. Adoption exempt). I would like to amend that to ‘1/2 surviving biological offspring’/person. If we are going to reduce population drastically, then genetic diversity is important for species health and survival. And all this assuming that we don’t indulge in tech like artificial embryos or create babies with pluripotent cells. It is important to find ways to preserve genetic material and gestation tech for said genetic material. Having said that…I believe that the first cloned humans are already alive and likely adults now. I refuse to believe or accept that countries that have scant regards for global ethical constraints will restrain themselves from exploring reproductive tech.
