Thomas Malthus Quotes

The power of population is indefinitely greater than the power in the earth to produce subsistence for man.

The perpetual tendency of the race of man to increase beyond the means of subsistence is one of the general laws of animated nature, which we can have no reason to expect to change.

Subsistence increases only in an arithmetical ratio.

Overpopulation is perhaps the biggest problem facing us, and immigration is part of that problem. It has to be addressed.

The whole surface of our globe can afford room and support only to such a number of all sorts of creatures, and by their doubling, trebling or any other multiplication of their kind, they must starve or devour one another. The world is now well-peopled ... neither too full nor too empty and if too many the length of life will be reduced …. plague and war may be, not only a just punishment of the sins of men, but also a wise means to keep the balance of mankind even.

Population, when unchecked, increases in a geometrical ratio. Subsistence increases only in an arithmetical ratio. A slight acquaintance with numbers will shew the immensity of the first power in comparison of the second.

To ensure a healthier and more abundant world, we simply must slow the world’s explosive growth in population.

One problem in Africa has been a small population. And the natural resources were large. So you could be as foolish as possible. But you didn’t die. You just remained there eating mangoes and bananas. Now the population in Africa is growing. So the idea that you can go on with idiotic policies is not sustainable. Because a big population needs answers.

… human population growth within the ecosystem was closely analogous to the growth of malignant tumor cells within an organism: that man was acting like a cancer on the biosphere. The multiplication of human numbers certainly seems wild and uncontrolled... Four million a month - the equivalent of the population of Chicago... We seem to be doing all right at the moment; but if you could ask cancer cells, I suspect they would think they were doing fine. But when the organism dies, so do they; and for our own, selfish, practical, utilitarian reasons, I think we should be careful about how we influence the rest of the ecosystem.

The Malthusian Theory - that mankind, for biological and sociological reasons, is so fertile, so fecund, that if you started out with the new continent and plenty of land for everybody, in several generations we would multiply our numbers.

The natural inequality of the two powers of population and of production in the earth, and that great law of our nature which must constantly keep their efforts equal, form the great difficulty that to me appears insurmountable in the way to the perfectibility of society.

One always returns to the fact that there are just too many of us, the population continues to rise and it's unsustainable.

The power of population is so superior to the power of the earth to produce subsistence for man, that premature death must in some shape or other visit the human race.

I generally avoid over-population arguments. But there's no question we're in population overshoot. The catch is we're not going to do anything about it. There will be no policy. The usual suspects: starvation, war, disease, will drive the population down. There's little more to say about that really, and it's certainly an unappetizing discussion, but it's probably the truth. In any case, we're in overshoot and we face vast resource scarcities.

There's going to be competition because there are not enough resources. Resources grow arithmetically, populations grow exponentially. You can't ever have enough resources and that's the foundation of this idea of competition.

[P]opulation, when unchecked, goes on doubling itself every twenty-five years, or increases in a geometrical ratio. ... [T]he means of subsistence, under circumstances the most favorable to human industry, could not possibly be made to increase faster than in an arithmetical ratio.

Human population growth is probably the single most serious long-term threat to survival. We're in for a major disaster if it isn't curbed...We have no option. If it isn't controlled voluntarily, it will be controlled involuntarily by an increase in disease, starvation and war.

Malthus has been buried many times, and Malthusian scarcity with him. But as Garrett Hardin remarked, anyone who has to be reburied so often cannot be entirely dead.

MALTHUSIAN, adj. Pertaining to Malthus and his doctrines, who believed in artificially limiting population, but found that it could not be done by talking. Herod of Judea, all the famous soldiers have been practical exponents of the Malthusian idea.

Short of nuclear war itself, population growth is the gravest issue the world faces. If we do not act, the problem will be solved by famine, riots, insurrection and war.

Unless we do things in this country to slow down our population, slow down our birth control, provide better water for people, provide power for people, we're gonna find out that the next wars are not going to be fought over diamonds, gold and political things.

Family planning is the only exit point of the land problem. No other solution is possible.

The idea that only a limited number of people can live in a country is profound illusion. It all depends on their cooperative and inventive power.

More goods and fewer people" is the slogan I should like to see carried at the head of humanity's march into the future.

If government knew how, I should like to see it check, not multiply the population.
