If the present growth trends in world population, industrialization, pollution, food production, and resource depletion continue unchanged, the limits to growth on this planet will be reached sometime within the next one hundred years. The most probable result will be a rather sudden and uncontrollable decline in both population and industrial capacity.

Why did I pick on the next nine years instead of the next 900 for finding a solution to the population crisis? One answer is that the world is rapidly running out of food. And famine, of course, could be one way to reach a death rate solution to the population problem. In fact, the battle to feed humanity is already lost, in the sense that we will not be able to prevent large famines in the next decade or so.

Les Nouveaux Gnostiques ne peuvent prouver qu'aux XXIe et XXIIe siècles la science ne trouvera pas de nouvelles sources d'énergie pour remplacer le pétrole, mais prouvent que l'on se fait illusion quand on croit le problème des énergies nouvelles aussi facile à résoudre que celui d'envoyer des hommes dans la Lune, et quand on attend des savants qu'ils inventent des forces motrices comme ils inventent des mécanismes ou des ordinateurs.
