My argument rests on two main propositions. First, the social, economic and developmental benefits of slower population growth rates have been substantially underestimated in recent decades. Because of the sustained effort of a handful of activists, the importance of this principle is be being belatedly rediscovered. For example, an enquiry into this question by the UK Parliament (released 2007) emphatically agreed with this. Summarising this evidence, Dr Martha Campbell, Professor John Cleland and two co-authors published a paper in the prestigious journal Science, called ‘Return of the Population Growth Factor,’ in March, 2007.
"the tide of the battle against hunger has changed for the better during the past three years. But tides have a way of flowing and then ebbing again. We may be at high tide now, but ebb tide could soon set in if we become complacent and relax our efforts. For we are dealing with two opposing forces, the scientific power of food production and the biologic power of human reproduction. Man has made amazing progress recently in his potential mastery of these two contending powers. Science, invention, and technology have given him materials and methods for increasing his food supplies substantially and sometimes spectacularly, as I hope to prove tomorrow in my first address as a newly decorated and dedicated Nobel Laureate. 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.
There can be no permanent progress in the battle against hunger until the agencies that fight for increased food production and those that fight for population control unite in a common effort. Fighting alone, they may win temporary skirmishes, but united they can win a decisive and lasting victory to provide food and other amenities of a progressive civilization for the benefit of all mankind."
