Food for thought

The question of whether there is sufficient food to feed the world's ever-increasing population has exercised the minds of philosophers, economists, agronomists, and demographers for many centuries. In 1798, Thomas Malthus, an English political economist, wrote a paper entitled An essay on the principle of population, which still provokes heated debate. Malthus suggested that the world's population, growing at a geometric rate, was increasing at a much faster rate than the world's food production, which only increased arithmetically. Malthus argued that if a balance between population and food was not maintained, and the world's population grew to a size that was not sustainable by contemporary food production practices, then the consequence would be widespread famine.
