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.

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.

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.

Adding a sterilant to drinking water or staple foods is a suggestion that seems to horrify people, most - than most proposals for involuntarily fertility control.

The capsule could be implanted at puberty and might be removable, with official permission, for a limited number of births.

Wildfires are a result of temperature conditions, of soil moisture conditions; and, of course, something has to start it.
