The 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.

If some individuals contribute to general social deterioration by overproducing children, and if the need is compelling, they can be required by law to exercise reproductive responsibility — just as they can be required to exercise responsibility in their resource-consumption patterns — providing they are not denied equal protection

To date, there has been no serious attempt in Western countries to use laws to control excessive population growth, although there exists ample authority under which population growth could be regulated.

A 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.

The need for de-development presents our economists with a major challenge. They must design a stable, low-consumption economy in which there is a much more equitable distribution of wealth than in the present one. Redistribution of wealth both within and among nations is absolutely essential if a decent life is to be provided for every human being.

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.
