It is an indictment of our society that, despite huge scientific advances in the last century, particularly in the production of food, millions of people, perhaps hundreds of millions, do not get enough to eat. The principal culprit is the Green movement, in its many species or fanaticisms. The Prince of Wales, who might be described as the most prominent Green man, has recently drawn attention to the destructive power of his ideology by attacking the growing of genetically modified crops, perhaps the largest step forward ever taken by mankind to reduce the cost of basic foodstuffs, and to increase their production and worldwide availability. I imagine if the Greens had lived in the 18th century they would have attacked the innovators who launched the agricultural revolution in England, which preceded the industrial one later in the century, and prevented mass starvation and chronic famine when the population rose sharply at the same time.
