Paul R. Ehrlich Quotes

I think as resources become more dear, we really need to consider population.

A finite world can support only a finite population; therefore, population growth must eventually equal zero.

We need to continue to decrease the growth rate of the global population; the planet can't support many more people.

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

We have to stabilize the population of this planet.

One of the most serious challenges to human destiny in the last third of this century will be the growth of population …. When future generations evaluate the record of. our time, one of the most important factors in their judgment will be the way in which we respond to population growth

Democracy cannot survive overpopulation.

I don't think anybody has the right to a huge family. There's already more people on the planet than our natural resources can even support, and if everybody were to have a high standard of living, we need three or four or five new planets to provide the resources. And this cannot be, so something has to change.

We're the ones causing global warming. In fact, what we ought to be saying is population growth is a major cause of it, so I hope to have a T-shirt out very, very soon: Stop global warming, use condoms.

There is a single theme behind all our work-we must reduce population levels.

The bigger the population gets, the more serious the problems become... We have to address the population issue. The United Nations, with the U.S. supporting it, took the position in Cairo in 1994 that every country was responsible for stabilizing its own population. It can be done. But in this country, it's phony to say 'I'm for the environment but not for limiting immigration.'

The human population can no longer be allowed to grow in the same old uncontrollable way. If we do not take charge of our population size, then nature will do it for us and it is the poor people of the world who will suffer most

In what I think is the most serious problem the world faces, which is the population explosion, we will come I think to a time when measures that are not even dreamt of now will become necessary.

Politically it would be terribly repressive to prevent people from having as many children as they want. But something's got to prevent it; and it won't be pleasant... We're still behaving in ways that have become disastrous... I don't think this helps us to survive... We're very species-centric... and now exist at the expense of every other form of life on Earth.

It's coming home to roost over the next 50 years or so. It's not just climate change; it's sheer space, places to grow food for this enormous horde. Either we limit our population growth or the natural world will do it for us, and the natural world is doing it for us right now.

Life and families and babies are all joyous gifts. But if we do not begin to truly account for our numbers, we will surely create an ecological crisis that will only lead to anguish and despair.

We are not overpopulated in an absolute sense; we've got the technology for 10 billion, probably 15 billion people, to live on this planet and live good lives. What we haven't done is developed our technology.

A billion could live off the earth; 6 billion living as we do is far too many, and you run out of planet in no time.

Man tends to increase at a greater rate than his means of subsistence.

There are probably already too many people on the planet.

The bigger question is how does a rogue species called humans - whose population just blew through the seven billion mark on it's way to nine billion members - manage to survive the next century on a planet with finite resources, without destroying its delicate balance in the process.

When is population going to become an accepted part of the food debate? If it's fine to encourage people to think about halving their meat consumption, can we really not cope with a conversation about how many children we have?

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

People who are not addressing the issues of population control are not seriously addressing the environment.

Development has to rise if population is going to increase, Otherwise people will starve and all kinds of other problems.
