I like the idea of this article but the point it makes are not well developed. Take the first: "That the food you eat is grown using synthetic fertilizers, and that this is needed for agricultural productivity, because all soil loses its fertility naturally over time if it is not deliberately replenished. That before we had modern agriculture, more than half the workforce had to labor on farms, just to feed the other half. That if synthetic fertilizer was suddenly lost, a mass famine would ensue and billions would starve." But what are the factors which drives the immense productivity? There is also this new machinery and selective breeding. Now what part in all of this does account for the immense productivity gain? Certainly it is not enough to give credit to the results of the Haber-Bosch process. Then the other point is that this immense productivity seems to have negative returns, as one can see in the USA, where the food makes people more fat and sick every year. Similar holds for the planet which slashed rain-forest for soybeans show.
