Green Machines

Projecting to the year 2000, Calder looks back on scientific breakthroughsespecially in agricultureof the late 20th century, such as the use of biogenetics to create food and energy, and their potential to alter social structures. The author of The English Channel and Einstein's Universe discusses how the techniques of modern biology can lead to light (food, water and shelter available to all) or darkness (nuclear winter). Examining the nation-states of this planet, he concludes that villages of a few thousand people, based on the Swiss system, would be an ideal unit for satisfactory living. Initially, Calder's vantage point (the future) makes the narrative seem forced; but his message is powerful enough to overcome any awkwardness. He offers exciting possibilities for a brave new world.
