“COULD FOOD shortages bring down civilization?” This was the title of an article in the May 2009 edition of the magazine Scientific American by Lester R. Brown.1 The article begins: “The biggest threat to global stability is the potential for food crises in poor countries to cause government collapse. Those crises are brought on by ever worsening environmental degradation.”
Brown is no fringe character; he has won numerous environmental awards and authored over 50 books addressing various aspects of the environmental crisis. Until 2000 he was president of the Worldwatch Institute, which publishes the influential and authoritative State of the World annual reports as well as the annual publication Vital Signs. A major preoccupation of Brown for more than three decades has been the idea that the world is perennially on the brink of running out of food because increases in human population are outstripping food supply. Now he is equally concerned that overpopulation is a major driver of ecological devastation. While Brown has been a resource-depletion doomsayer for decades, he is echoed by many others. Neo-Malthusian arguments are resurfacing with a vengeance as explanations for the recent global food crisis and, even more so, among people genuinely concerned by the ongoing, and indeed accelerating, destabilization of planetary ecosystems.
The return of Malthus
A number of liberal writers and publications have raised the specter of growing population as an unpleasant yet necessary topic of conversation. Johan Hari, a writer for the Independent, posed the question in one of his columns last year, “Are there just too many people in the world?” While noting that Malthusian predictions have consistently been wrong and often used as arguments against the poor, he nevertheless concludes that, “After studying the evidence, I am left in a position I didn’t expect. Yes, the argument about overpopulation is distasteful, often discussed inappropriately, and far from being a panacea-solution—but it can’t be dismissed entirely. It will be easier for 6 billion people to cope on a heaving, boiling planet than for nine or 10 billion.”2 An editorial in the Guardian newspaper from March of this year, entitled “The Malthusian question,” even while rejecting the more outrageous population-reduction arguments and overt Malthusianism of organizations such as the Optimum Population Trust, confirms in alarmist terms the relevance of population-based arguments to environmental decay:
Yet human numbers continue to swell, at more than 9,000 an hour, 80 million a year, a rate that threatens a doubling in less than 50 years. Land for cultivation is dwindling. Wind and rain erode fertile soils. Water supplies are increasingly precarious. Once-fertile regions are threatened with sterility. The yield from the oceans has begun to fall. To make matters potentially worse, human numbers threaten the survival of other species of plant and animal. Humans depend not just on what they can extract from the soil, but what they can grow in it, and this yield is driven by an intricate ecological network of organisms. Even at the most conservative estimate, other species are being extinguished at 100 to 1,000 times the background rate observable in the fossil record.”3
The notion that population growth is the foremost cause of environmental degradation and societal destabilization is raised in the Summer 2009 issue of Scientific American’s publication, Earth 3.0—Solutions for Sustainable Progress. The cover article, titled “Population and Sustainability,” by Robert Engelman, vice president for programs at the Worldwatch Institute, poses the question: Can we avoid limiting the number of people? It begins:
In an era of changing climate and sinking economies, Malthusian limits to growth are back—and squeezing us painfully. Whereas more people once meant more ingenuity, more talent and more innovation, today it just seems to mean less for each [emphasis in original].4
Engelman does not believe that coercive population control methods are necessary, primarily because, as he notes, they haven’t worked. Nevertheless, he urges governments, institutions and people to consider how we can best reduce population growth in order to conserve resources, reduce our ecological footprint, and prevent conflict over worsening environmental conditions.
