A Dangerous Road: A New Technological Revolution in Food

Back in 1968 The Population Bomb, by Paul and Anne Ehrlich, created a sensation with its predictions of famine and Malthusian disaster. Ultimately their predictions were proven to be incorrect, at least in terms of the time-frame that the authors suggested. What the Ehrlichs had failed to take into account was the so-called Green Revolution in agriculture that had begun in the 1950s but was a long way from reaching its potential impact on food production. Technological innovation, through new methods, new crop varieties, the use of oil-powered machinery, artificial pesticides and fertilizers transformed farming across the world, particularly in developing countries where it had not been utilized before.

Greater efficiency in production meant that as the human population continued expanding the production of food supplies would also expand to meet and surpass the necessary levels to sustain the continued growth of humanity. This revolution in agriculture was hailed as a miraculous success, which is perhaps true in the sense that its rollout probably saved millions or even billions of people from death by starvation and diseases caused by malnutrition. Paul Ehrlich, himself, acknowledges that he was indeed wrong but still believes that his fundamental theory was correct and that we have merely deferred an inevitable disaster.

Some sixty years after the Green Revolution began we now understand that the effects of this dramatic change are not all positive. While it…
