Only one rational path is open to us - simultaneous de-development of the [overdeveloped countries] and semi-development of the underdeveloped countries (UDCs), in order to approach a decent and ecologically sustainable standard of living for all in between. By de-development we mean lower per-capita energy consumption, fewer gadgets, and the abolition of planned obsolescence.
John HoldrenWe are not, of course, optimistic about our chances of success. Some form of ecocatastrophe, if not thermonuclear war, seems almost certain to overtake us before the end of the century. (The inability to forecast exactly which one - whether plague, famine, the poisoning of the oceans, drastic climatic change, or some disaster entirely unforeseen - is hardly grounds for complacency.)
John HoldrenThe development of a long-term sterilizing capsule that could be implanted under the skin and removed when pregnancy is desired opens additional possibilities for coercive fertility control. The capsule could be implanted at puberty and might be removable, with official permission, for a limited number of births.
John HoldrenA program of sterilizing women after their second or third child, despite the relatively greater difficulty of the operation than vasectomy, might be easier to implement than trying to sterilize men.
