In fact, the battle to feed humanity is already lost, in the sense that we will not be able to prevent large-scale famines in the next decade or so.” - Paul Ehrlich, The Population Bomb, 1968 350 World Food Production 300 1961-2009 313 (1961=100) 250 Total Food ProductionPopulation 220 200 150 Per Capita Food Production 141 100 Source: Food and Agriculture Organization 50 1960 1970 1980 1990 2000 2010 400 India Food Production 350 1961-2009 361 300 (1961=100) 262 250 Total Food ProductionPopulation 200 150 Per Capita Food Production 137 100 50 Food and Agriculture Organization 1960 1970 1980 1990 2000 2010 400 Sub-Saharan Africa 359 350 Food Production 1961-2009 1961=100 335 300 Population 250 200 Total Food Production 150 100 93 Per Capita Food Production 50 1960 1970 1980 1990 2000 2010 100 Percent in Poverty, 1981-2005 Low and Middle Income Countries 80 (in 2005 US dollars) 60 52% < $1.25 per day 40 20 25% World Bank estimates 0 1981 1984 1987 1990 1993 1996 1999 2002 2005 100 Percent in Poverty, 1981-2005 80 <$1.25 per day 60 Sub-Saharan Africa South Asia 50,9 40 40,3 East Asia 20 Latin America 16,8 8,2 0 World Bank estimates 1981 1984 1987 1990 1993 1996 1999 2002 2005 “If you are prepared to pay me now the current market price for $1,000 worth of any mineral you name, I will agree to pay you the market price of the same amount of that raw material on any future date you now specify.” Julian Simon, 1981 The Ultimate Resource Julian Simon’s bet with Paul Ehrlich Total inflation- adjusted cost fell from $1000 in 1980 to $618 in 1990 300 Real prices of metals1960-2010 (1980=100) 250 Simon-Ehrlich Nickel 200 bet 150 Copper 100 Chromium 50 Tungsten Tin 0 Source: USGS 1960 1970 1980 1990 2000 2010 200 Real commodity prices 1960-2010 (1980=100) 150 Food Non-Energy 100 50 0 Source: World Bank 1960 1970 1980 1990 2000 2010 400 Food Price Index (2000=100) 350 January 300 2011 243 250 200 150 100 50 0 Source: World Bank 1960 1970 1980 1990 2000 2010 To be continued after we hear from Stan Becker and hear the results of the wager … Population group chosen by Stan to receive David’s $194 donation Population Media Center Mission: “To use entertainment-education and mass media to promote social and cultural change by addressing the interconnected issues of the full rights of women and girls, population, and the environment.

They do not give good incentives to produce fewer greenhouse gasses. • Poverty reduction is still very uneven around the world, with Africa facing continued challenges. .

  • Method Versus Methodology: a Note on 'The Ultimate Resource'
    Method versus Methodology: A Note on The Ultimate Resource Science appears but what in truth she is, Not as our glory and our absolute boast, But as succedaneum, and a prop To our infirmity. No officious slave Art thou of that false secondary power By which we multiply distinctions, then Deem that our boundaries are things That we perceive, and not that we have made. -William Wordsworth, "The Prelude" n discussing the thought of Albert Einstein in the second course of his Gifford Lectures at Edinburgh, Professor Stanley L. Jaki draws an impor- I tant distinction between the great physicist's method and his methodology. On the one hand, says Jaki, Einstein represented himself as an advocate of the "sensationism" of Ernst Mach, according to which view the existence of an objective cosmos underlying the subjective sensations of the physicist was expressly denied; whereas, on the other hand, the spectacular breakthrough represented by special (and later, general) relativity was the result of Einstein's conviction of the existence of a universal natural order, which was intelligible to man in a manner quite independent of his cultural or historical position.' Thus, the manner of Einstein's approach to reality (his method) was not at all consistent with his own reflection on the manner of his approach to reality (his methodology). The possibility of such confusion as this is but one result of the fact em- phasized by William James that the process of our consciousness is one thing and our critical reflection (through the vehicle of memory) on that process quite an~ther.~Just as "systematic reflection on the consciousness is a late event in The Ultimate Resource by Julian L.

  • The Bet: Paul Ehrlich, Julian Simon, and Our Gamble Over Earth’S Future
    23-215-MILLER_FINAL 5.13.14 5/13/2014 12:40 PM THE BET: PAUL EHRLICH, JULIAN SIMON, AND OUR GAMBLE OVER EARTH’S FUTURE By Paul Sabin, Yale University Press 2013 Reviewed by Richard B. Miller* It seems a matter of common sense that infinite resources do not exist, and we should, therefore, use our resources carefully. But it is a mistake to understate the impact of human ingenuity and market economics on the demand for resources we are inclined to think of as essential. This more complex truth was well understood by the Saudi Arabian oil minister, Sheikh Zaki Yamani, who famously stated that “[the] Stone Age did not end for lack of stone, and the Oil Age will end long before the world runs out of oil.”1 The story of this more complex truth about resource scarcity and its relationship to the modern environmental movement is well told by Paul Sabin in The Bet.2 The Bet has lessons for today’s debate over climate change and should serve as a cautionary tale for activists on either side. The Bet recounts the rivalry between Paul Ehrlich, the biologist who wrote The Population Bomb3 in 1968, and Julian Simon, an economist who wrote The Ultimate Resource4 in 1981. Ehrlich warned of the dangers of overpopulation and the destruction of the planet while Simon celebrated population growth and the ingenuity that enables humans to adapt to changing circumstances. Ehrlich relied on the simple logic that resources are finite, claiming that increased population would lead to mass starvation. Notwithstanding his doomsday message, he was immensely popular

  • Empower Women, Save the Planet? Science, Strategy, and Population-Environment Advocacy
    Empower Women, Save the Planet? Science, Strategy, and Population-Environment Advocacy By Jade Sasser A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Environmental Science, Policy & Management in the Graduate Division of the University of California, Berkeley Committee in charge: Professor Nancy Lee Peluso, Chair Professor Louise Fortmann Professor Carolyn Finney Professor Lawrence Cohen Spring 2012 Empower Women, Save the Planet? Science, Strategy, and Population-Environment Advocacy © 2012 by Jade Sasser Abstract Empower Women, Save the Planet? Science, Strategy, and Population-Environment Advocacy by Jade Sasser Doctor of Philosophy in Environmental Science, Policy, and Management University of California, Berkeley Professor Nancy Peluso, Chair This dissertation is about the problems of global population and women’s fertility as constructed, circulated and contested among a network of American environmental actors. The first decade of the new millennium witnessed an upsurge in environmentalist attention to population trends, particularly in the context of widespread attention to climate change. Using ethnographic research conducted among a network of U.S. foreign aid donors, environmental, population and family planning NGO managers, and college youth activists, this dissertation asks the questions: What- and who- is driving the renewed focus on population growth as a driver of ecological crisis? What strategies are being used to drive a linked population-environment development agenda forward, and what effects do these strategies have on population science, policy, and political debates? I argue that, rather than reprise familiar neo-Malthusian arguments, these actors draw on scientific knowledge and social justice frameworks, to position population- environment advocacy in the realm of progressive politics.

  • Overpopulation– the Modern Denial
    CHAPTER 2 Overpopulation– the modern denial The word overpopulation was brought into the modern pub- lic consciousness in 1968 by a book called The Population Bomb written by Paul Ehrlich. The book was a warning to the world that the human population was a ticking time bomb about to explode. The book badly missed the mark with its predictions of resource shortages and famine. For example, Ehrlich predicted that four billion people would starve to death in the 1980s. Based on that prediction, he also called for some highly unpopular measures to reduce our population growth. To ice the cake, he made a bet with an economist named Julian Simon about the price of five metals over a ten-year period. Ehrlich said the price would go up as a result of dwindling resources and Simon said the price would drop. The price dropped. Ehrlich paid up. W hy Ehrlich thought that new sources for those metals would not be found or that manufacturers would not make compromises to compensate for shortages is beyond me. As an engineer at Boe- ing, I often altered a design to use high strength aluminum instead of titanium because the cost of titanium was too high. At one time, most sources of titanium were in the Soviet Union. W e used titanium extensively after the fall of the Berlin wall. I recently met Paul Ehrlich at a signing for his latest book One with Nineveh. I listened to him speak for an hour. He is an impressive figure, tall, vigorous, with a deep voice and a tre- mendous sense of humor.

Sustainability: An Interdisciplinary Guide JOHN PEZZEY UK CEED Research Fellow Department of Economics University of Bristol 8 Woodland Road Bristol BS8 1TN, UK ABSTRACT: A definition of sustainability as maintaining ‘utility’ (average human wellbeing) over the very long term future is used to build ideas from physics, ecology, evolutionary biology, anthropology, history, philosophy, economics and psychology, into a coherent, interdisciplinary analysis of the potential for sustaining industrial civilisation. This potential is highly uncertain, because it is hard to know how long the ‘technology treadmill’, of substituting accumulated tools and knowledge for declining natural resource inputs to production, can continue. Policies to make the treadmill work more efficiently, by controlling its pervasive environmental, social and psychological external costs, and policies to control population, will help to realise this potential. Unprecedented levels of global co-operation, among very unequal nations, will be essential for many of these policies to work effectively. Even then, tougher action may be required, motivated by an explicit moral concern for sustainabil- ity.

  • Constructing Environmental Conflicts from Resource Scarcity
    Constructing Environmental Conºicts from Resource Scarcity • Peter M. Haas* PeterConstructing M. Haas Environmental Conºicts from Resource Scarcity Resource scarcity and environmental security are long standing themes in inter- national relations and security studies. These are important ideas because they inform or justify US and other countries’ foreign policies. The commitment of resources, and possibly intervention, is warranted against these justiªcations. Claims that human societies are exhausting scarce resources, and that this pro- cess may contribute to armed conºict with and between states, has been part of the economics and politics literatures for at least 130 years. Yet an analytic focus on material scarcity as a provocation for conºict is but a meager part of much richer approaches to understanding conºict and cooperation more generally. The question is, can these doctrines of resource scarcity and environmen- tal security bear the weight of justifying US interventions? My argument is that these doctrines are ºawed, and are selectively invoked by policy makers and in- attentive academics in order to justify preexisting state goals. My interest here is why they enjoy such resilience, despite the fact that each is widely contested within the relevant policy communities, and that there are many other ways of formulating interesting questions about resource scarcity. The attractiveness of these doctrines is not solely the nature of the argu- ment they make, but rather their afªnity to the values and beliefs invoked by the person making the argument. We have a lot of names for such things, including myths, mental models, worldviews, frames, narratives, ideologies, paradigms, epistemes, referentielles, or worldviews, all of which can be encompassed in a broad view of “discourses.” Discourses impart meaning to an ambiguous policy domain.

Received: 9 November 2010; in revised form: 6 December 2010 / Accepted: 15 December 2010 / Published: 7 January 2011 Abstract: A study of sustainability needs to consider the role of all forms of capital—natural, biological, social, technological, financial, cultural—and the complex ways in which they interact. All forms of capital derive their value, utility and application from human mental awareness, creativity and social innovation. This makes human capital, including social capital, the central determinant of resource productivity and sustainability. Humanity has entered the Anthropocene Epoch in which human changes have become the predominant factor in evolution. Humanity is itself evolving from animal physicality to social vitality to mental individuality. This transition has profound bearing on human productive capabilities, adaptability, creativity and values, the organization of economy, public policy, social awareness and life styles that determine sustainability. This article examines the linkages between population, economic development, employment, education, health, social equity, cultural values, energy intensity and sustainability in the context of evolving human consciousness. It concludes that development of human capital is the critical determinant of long-term sustainability and that efforts to accelerate the evolution of human consciousness and emergence of mentally self-conscious individuals will be the most effective approach for ensuring a sustainable future.
