Even after more than ten years of trying to raise awareness about certain overlooked research, my focus remains riveted on the skyrocketing growth of absolute global human population and scientific evidence from Hopfenberg and Pimentel that the size of the human population on Earth is a function of food availability. More food for human consumption equals more people; less food for human existence equals less people; and no food, no people. This is to say, the population dynamics of the human species is essentially common to, not different from, the population dynamics of other living things.
UN Secretary-General Mr. Kofi Annan noted in 1997, "The world has enough food. What it lacks is the political will to ensure that all people have access to this bounty, that all people enjoy food security."
Please examine the probability that humans are producing too much, not too little food; that the global predicament humanity faces is the way increasing the global food supply leads to increasing absolute global human population numbers. It is the super-abundance of unsustainable agribusiness harvests that are driving population numbers of the human species to overshoot, or explode beyond, the natural limitations imposed by a relatively small, evidently finite, noticeably damaged planet with the size, composition and ecology of Earth.
The spectacular success of the Green Revolution over the past 40 years has "produced" an unintended and completely unanticipated global challenge, I suppose: the rapidly increasing supply of food for human consumption has given birth to a human population bomb, which is exploding worldwide before our eyes. The most formidable threat to future human well being and environmental health appears to be caused by the unbridled, corporate overproduction of food on the one hand and the abject failure of the leaders of the human community to insist upon more fair and equitable redistribution of the world's food supply so that "all people enjoy food security."
We need to share (not overconsume and hoard) as well as to build sustainable, human-scale farming practices (not corporate leviathans), I believe.
For a moment let us reflect upon words from the speech that Norman Bourlaug delivered in 1970 on the occasion of winning the Nobel Prize. He reported, "Man also has acquired the means to reduce the rate of human reproduction effectively and humanely. He is using his powers for increasing the rate and amount of food production. But he is not yet using adequately his potential for decreasing the rate of human reproduction. The result is that the rate of population increase exceeds the rate of increase in food production in some areas."
Plainly, Norman Bourlaug states that humanity has the means to decrease the rate of human reproduction, but is choosing not to adequately employ this capability to sensibly limit human population numbers. He also notes that the rate of human population growth surpasses the rate of increase in food production in some areas (my emphasis. Dr. Bourlaug is specifically not saying the growth of global human population numbers exceeds global production of food.
According to recent research, population numbers of the human species could be a function of the global growth of the food supply for human consumption. This would mean that the global food supply is the independent variable and absolute global human population numbers is the dependent variable; that human population dynamics is most similar to the population dynamics of other species. Perhaps the human species is not being threatened in our time by a lack of food. To the contrary, humanity and life as we know it could be inadvertently put at risk by the determination to continue the dramatic, large-scale overproduction of food, such as we have seen occur in the past 40 years.
Recall Dr. Bourlaug's prize winning accomplishment. It gave rise to the "Green Revolution" and to the extraordinary increases in the world's supply of food. Please consider that the sensational increases in humanity's food supply occasioned by Dr. Bourlaug's great work gave rise to an unintended and completely unanticipated effect: the recent skyrocketing growth of absolute global human population numbers.
We have to examine what appear to be potentially disastrous effects of increasing large-scale food production capabilities (as opposed to small-scale farming practices) on human population numbers worldwide between now and 2050. If we keep doing the "big-business as usual" things we are doing now by maximally increasing the world's food supply, and the human community keeps getting what we are getting now, then a colossal ecological wreckage of some unimaginable sort could be expected to occur in the fairly near future.
It may be neither necessary nor sustainable to continue increasing food production to feed a growing population. As an alternative, we could carefully review ways for limiting increases in the large-scale corporate production of food; for providing broad support of small-scale farming practices; for redistributing more equitably the present overly abundant world supply of food among the members of the human community; and for immediately, universally and safely following Dr. Bourlaug's recommendation to "reduce the rate of human reproduction effectively and humanely."
Steve Salmony is a self-proclaimed global citizen, a psychologist and father of three grown children. Married 38 years ago. In 2001 Steve founded the AWAREness Campaign on The Human Population to raise consciousness of the colossal threat that the unbridled, near exponential growth of absolute global human population numbers poses for all great and small living things on Earth in our time. His quixotic campaign focuses upon the best available science of human population dynamics in order to save the planet as a place fit for habitation by children everywhere.

It appears to me that people are beginning to get used to discussing the human overpopulation of Earth, despite conspicuous resistance to discussions of this kind. For a moment imagine that human overpopulation of a living Earth is like a live human organism with lung cancer. Please note that although it is exceedingly difficult to talk about “the big C”, it is much more demanding to speak out about the cause of the lung cancer: smoking tobacco products. Similarly, despite the challenges we have to speaking out loudly and clearly about the skyrocketing increase of absolute global human population numbers during my lifetime, it is much more difficult say anything about what might be causing global human population growth. Of course that brings us to human population dynamics. Perhaps this is the last of the last taboos. The denial of the science of human population dynamics appears to me as one of the most colossal failures of nerve in human history. The abandonment of intellectual honesty, moral courage responsible action is unconscionable.
One day human population dynamics will become a topic of open discussion, that is certain. Global gag rules will be eschewed rather than promulgated. When that time comes, I trust it is not too late to make a difference in the lives of our children, who are probably going to be unimaginably victimized not only by the arrogance, folly and greed of their elders but also by their cowardice.
Lester Brown reminds us now that "civilization’s foundation is eroding". He and we pay careful attention to the distinctly human-driven symptoms of what ails us and report them everywhere; but when will we examine the possible causes of the ailment itself and report findings of what appears to be a non-recursive biological problem? If the human overpopulation of Earth is the problem, when is extant scientific evidence of human population dynamics to become the object of rigorous scrutiny, careful analysis and professional reports?
Many too many experts possess scientific knowledge of human population dynamics and human overpopulation of the Earth, I believe. They have remained electively mute. They know and could do better; they have both the tools and the empirical evidence at their fingertips; they are abdicating their responsibility in raising awareness of the those that still do not yet see and understand the human-induced aspects of the global predicament looming before humanity.
Many experts have had a multitude of opportunities to comment on human population dynamics and the human overpopulation of Earth in professional conferences like those sponsored every four years by the International Union for the Scientific Study of Population and in an array of speciality journals dedicated to human ecology, population biology, human demography, etc. The experts have uniformly refused. Their abject failure to respond more ably to the challenges presented to humanity in our time is woefully inadequate and inexcusable. It would be unfortunate if the silence of so many was ever construed as giving consent to this ignominous behavior.

If leaders keep choosing to outrageously overconsume and hoard; to relentlessly overproduce unnecessary stuff; to over-grow businesses to the point of "too big to succeed"; and to silently condone the unbridled increase of absolute global human population numbers in the planetary home we are blessed to inhabit, as so many leaders are adamantly advocating and recklessly pursuing now, what chance do the children have for a good enough future? This way forward looks like a "primrose path". For the short term the way forward looks great, but foresighted people can already discern forbidding, human-driven, global ecological dangers in the offing. Human overconsumption, overproduction and overpopulation activities worldwide can readily be seen mortgaging the children's future and threatening their birthright.
Can we describe "sustainable behavioral repertoires" for individuals that elders can begin to exemplify and children can emulate? Can we define the elements and develop the plans for sustainable business enterprises?
