- Ethical Implications of Carrying Capacity, by Garrett Hardin.
The carrying capacity of a particular area is defined as the maximum number of a species that can be supported indefinitely by a particular habitat, allowing for seasonal and random changes, without degradation of the environment and without diminishing carrying capacity in the future.
- A Special Moment in History, article by Bill Mckibben, Atlantic Monthly, May 1998.
World population is exceeding carrying capacity.
- Carrying Capacity as an Ethical Concept, essay on Garret Hardin's concepts.
In an uncrowded world there may be no ethical need for the ecological concept of the carrying capacity. But ours is a crowded world. We need this concept if we are to minimize human suffering in the long run (and not such a very long run at that). How Western man has pretty well succeeded in locking himself into a suicidal course of action by developing and clinging to a concept of the absolute sanctity of life is a topic that calls for deep inquiry.
- Feeding the Population Monster, Ronald Bleier; March 1997.
Tobias writes: "... the current size of the human population has wreaked unprecedented damage on the biosphere, and is going to accelerate that damage. Millions of plant and animal species have been driven to extinction. ... A billion people are hungry, morning, noon and night. The ozone layer is thinning, with consequences that are lethal for every living organism. The air, water, and soil across the planet have been fouled. The forests in many countries are gone or nearly gone. And the mammary glands of every mother on Earth are now infiltrated with DDT and other harmful chemicals. These essential facts -- truths that distinguish this century from any other in our history -- are all the byproduct of uncontrolled human fertility and thoughtless behavior. Even if we should manage to merely double our population size by the next century [to reach] 11 billion  the ecological damage will be catastrophic, unimaginable (p. 426)"
- The Implications of the North American Free Trade Agreement for Workers, by F. Ray Marshall, Center for Immigration Studies, February 1993.
The United States and Mexico should adopt high-productivity, high-wage competitiveness policies and make labor and environmental standards part of the NAFTA process. The rational for trade-linked international labor and environmental standards is thus the same as for enforceable labor or environmental protections in domestic markets. The moral reason is to limit the exploitation of workers and the environment.
- Food, Land, Population, and the U.S. Economy, by David Pimentel, Cornell University and Mario Giampietro Isiituto Nazionale dell, Nutrizione, Rome.
The United States is in a privileged situation compared to other nations in the world. At the same time, the United States is seriously risking loosing this privilege if more attention is not given to the control of population growth (including immigration), the sustainable management of natural resources, and the development of alternative energy sources.
- How and Why Journalists Avoid the Population-Environment Connection.
Recent surveys show that Americans are less concerned about population than they were 25 years ago, and they are not connecting environmental degradation to population growth. Journalists are aware of the controversial nature of the population issue, and prefer to avoid it if possible.

- How Many Americans Can the Earth Support?, by David Pimentel.
Based on the current growth rate, the present U.S. population of more than 270 million is projected to double to 540 million within the next 70 years. In addition, the world population -- about 6 billion -- is projected to double within just 50 years (again, based on current rates of growth). The growing imbalance between the increasing world population and the finite amount of Earth's resources that support human life is reason for grave concern.
How Many People Should the Earth Support?,
by Ross McCluney.
Using a more ecocentric definition, what would be the desirable number of humans for the planet, rather than just how many we might be able to cram into "the pasture" on a "sustainable" basis.
- How To Influence Fertility: The Experience So Far by John R. Weeks.
In this country, our complacency about low fertility has allowed national leaders to sidestep the population issue. Yet, every addition to the population in a country like the United States yanks a vastly disproportionate hunk out of the world's storehouse of known resources. For this reason, policies that affect population growth in the U.S. have a major long-term effect on all aspects of the world's ecosystem. We should assist globally in every way we can and we should lead by example.
- Impact of Population Growth on Food Supplies and the Environment, by David Pimentel, Xuewen Huang, Ana Cordova, and Marcia Pimentel.
As the world population expands, the food problem will become increasingly
severe, conceivably with the numbers of malnourished reaching 3 billion.
- Is Humanity Suicidal?, by Edward O. Wilson.
Unlike any creature that lived before, humans have become a geophysical force, swiftly changing the atmosphere and climate as well as the composition of the world's fauna and flora.
Now in the midst of a population explosion, this species has doubled in number to more than 6 billion during the past 50 years. It is scheduled to double again in the next 50 years. No other single species in evolutionary history has even remotely approached the sheer mass in protoplasm generated by humanity.

- Reflections on Sustainability, Population Growth, and the Environment, by Albert Bartlett.
The main message of the paper is contained in the first two Laws of Sustainability, which point out that in any society, population growth cannot be sustained, and that the larger the population, the more difficult it will be for the society to achieve sustainability.
- On The Threshold: Environmental Changes as Causes of Acute Conflict, Thomas F. Homer-Dixon, University of Toronto.
Developing countries are likely to be affected sooner and more severely by environmental change than rich countries. By definition, they do not have the financial, material, or intellectual resources of the developed world; furthermore, their social and political institutions tend to be fragile and riven with discord. It is probable, therefore, that developing societies will be less able to apprehend or respond to environmental disruption.
Is There a Population Problem?, by Al Bartlett.

- Optimum Human Population Size, Gretchen C. Daily, University of California, Anne H. Ehrlich and Paul R. Ehrlich, Stanford University; July 1994.
Although the tremendous size and rate of growth of the human population now influence virtually every aspect of society, rarely does the public debate, or even consider, the question of what would be an optimum number of human beings to live on Earth at any given time?

Regionwide Planning Will Make the Problems Worse, by Albert A. Bartlett.
Clearly states why both "smart growth" and "dumb growth" will destroy the environment. "Population growth is causing all the enumerated problems but, as I will demonstrate, regional planning is not a 'solution' because it will enlarge the problems and make them all worse."

The Environmental Movement's Retreat from Advocating U.S. Population Stabilization;
by Roy Beck and Leon Kolankiewicz.
This article examines in detail the events leading to abandonment
of domestic population stabilization efforts by major environmental
organizations. ZPG and Sierra Club are used as case studies in the
article. It is highly recommended to all population activists,
environmentalists, and funders of environmental organizations.

The Massive Movement to Marginalize the Modern Malthusian Message, Al Bartlett.
Originally published in
The Social Contract.
The article discusses how those wishing to downplay the seriousness of overpopulation have attempted to marginalize the population message.

The author disproves cornucopians who claim that the earth offers an inexhaustible supply of resources for humankind.
The Tightening Conflict: Population, Energy Use, and the Ecology of Agriculture, by Mario Giampietro and David Pimentel.
In the last half century the technological development of agriculture has dramatically changed the performance of farming in both positive and negative ways.
- There is No Global Population Problem by Garrett Hardin.
"The moral is surely obvious: Never globalize a problem if it can possibly be solved locally. It may be chic but it is not wise to tack the adjective global onto the names of problems that are merely widespread - for example, 'global hunger,' 'global poverty,' and the 'global population problem.' We will make no progress with population problems, which are a root cause of both hunger and poverty, until we deglobalize them.
Populations, like potholes, are produced locally and, unlike atmospheric pollution, remain local - unless some people are so unwise as to globalize them by permitting population excesses to migrate into the better-endowed countries. Marx's formula, 'to each according to his needs,' is a recipe for national suicide. 'Don't try to solve your population problem by exporting your excess people to us.' All nations should take this position, and most do. Unfortunately, many Americans seem to believe that our nation can solve everyone else's population problems."
