This article is fascinating, written in 1983. While he wasn’t ‘dead on’ he was pretty damn close, here is a highlight;
First: Population will be continuing to increase for some years after the present and this will make the pangs of transition even more painful. Governments will be unable to hide from themselves the fact that no problem can possibly be solved as long as those problems continue to be intensified by the addition of greater numbers more rapidly than they can be dealt with.
Efforts to prevent this from happening by encouraging a lower birthrate will become steadily more strenuous and it is to be hoped that by 2019, the world as a whole will be striving toward a population plateau.
Second: The consequences of human irresponsibility in terms of waste and pollution will become more apparent and unbearable with time and again, attempts to deal with this will become more strenuous. It is to be hoped that by 2019, advances in technology will place tools in our hands that will help accelerate the process whereby the deterioration of the environment will be reversed.
Third: The world effort that must be invested in this and in generally easing the pains of the transition may, assuming the presence of a minimum level of sanity among the peoples of the world, again not a safe assumption, weaken in comparison the causes that have fed the time-honoured quarrels between and within nations over petty hatred and suspicions.
In short, there will be increasing co-operation among nations and among groups within nations, not out of any sudden growth of idealism or decency but out of a cold-blooded realization that anything less than that will mean destruction for all.
I find his thoughts on overpopulation and global warming ring true.
