Paul R. Ehrlich Quotes

Interstellar transport for surplus people presents an musing perspective. Since the ships would take generations to reach most stars, the only people who could be transported would be those willing to exercise strict birth control. Population explosions on space ships would be disastrous. Thus we would have to export our responsible people, leaving the irresponsible at home on Earth to breed.

In brief, death control goes with the grain, birth control against it.

Too many rich people in the world is a major threat to the human future, and cultural and genetic diversity are great human resources.

The day may come when the obese people of the world must give up diets, since metabolizing their fat deposits will lead to DDT poisoning. But, on the bright side, it is clear that fewer and fewer people in the future will be obese!

A series of things have come up since then that have made the problem incredibly grimmer…. The ozone hole… acid rain…. Three hundred million people have starved to death since THE POPULATION BOMB was written. The famines weren’t as large as agriculturists thought they would be… due to the spread of… Green Revolution technology into the poor countries…. What makes us nervous right now is that we’re faced with again having to do something desperate to increase our food production greatly.... In 1965 we knew exactly how to do it, the question was could we deploy it fast enough—Today we have nothing left to deploy—that’s very scary.... As a species we’re not able to live on our income; we’re living on our capital, our deep rich agricultural soils are being destroyed, water is being overpumped, and our biodiversity, our life support system—we’re already far beyond what we can support.

Overdrafts on aquifers are one reason some of our geologist colleagues are convinced that water shortages will bring the human population explosion to a halt. There are substitutes for oil; there is no substitute for fresh water.

Culture can be loosely defined as the body of non-genetic information which people pass from generation to generation.

If I were a gambler, I would take even money that England will not exist in the year 2000 (Quote from 1969).

Solving the population problem is not going to solve the problems of racism… of sexism… of religious intolerance… of war… of gross economic inequality—But if you don’t solve the population problem, you’re not going to solve any of those problems. Whatever problem you’re interested in, you’re not going to solve it unless you also solve the population problem. Whatever your cause, it’s a lost cause without population control.

In fact, giving society cheap, abundant energy at this point would be the moral equivalent of giving an idiot child a machine gun. With cheap, abundant energy, the attempt clearly would be made to pave, develop, industrialize, and exploit every last bit of the planet—a trend that would inevitably lead to a collapse of the life-support systems upon which civilization depends.

As I’ve said many times, ‘perpetual growth is the creed of the cancer cell’.

The idea that we can just keep growing forever on a finite planet is totally imbecilic.... Julian Simon, a professor of junkmail marketing, and his kind, think technology will solve everything.... We can use up the Earth then we can just jump into spaceships and fly somewhere else.... Technology does nothing to solve problems of biodiversity or living space or arable cropland.... Fresh water and arable cropland are finite resources.... We are already far beyond what we can support sustainably.... The provincial view you get from someone living in some wealthy American East Coast city is wildly different from reality. Most of the world is tropical, hungry and poor. Visit the developing world and southern hemisphere and you get a very different view of reality.

To start, make modern contraception and back-up abortion available to all and give women full equal rights, pay and opportunities with men. I hope that would lead to a low enough total fertility rate that the needed shrinkage of population would follow. [But] it will take a very long time to humanely reduce total population to a size that is sustainable.

Few problems are less recognized, but more important than, the accelerating disappearance of the earth's biological resources. In pushing other species to extinction, humanity is busy sawing off the limb on which it is perched.

Actually, the problem in the world is that there are too many rich people.
