A massive campaign must be launched to restore a high-quality environment in North America and to de-develop the United States...De-development means bringing our economic system (especially patterns of consumption) into line with the realities of ecology and the global resource situation...Redistribution of wealth both within and among nations is absolutely essential, if a decent life is to be provided for every human being.

We 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.)

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.

Humanity cannot afford to muddle through the rest of the twentieth century; the risks are too great, and the stakes are too high. This may be the last opportunity to choose our own and our descendants’ destiny. Failing to choose or making the wrong choices may lead to catastrophe. But it must never be forgotten that the right choices could lead to a much better world.

The e-mails are mainly about a controversy over a particular data set and the ways a particular small group of scientists have displayed that dataset.

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.

There exists ample authority under which population growth could be regulated...It has been concluded that compulsory population-control laws, even including laws requiring compulsory abortion, could be sustained under the existing Constitution if the population crisis became sufficiently severe to endanger the society.
