Computers should never have acquired the exalted status they now have. Fascinating and invaluable as they are, even the most advanced have less brain power than a three-year-old. But, they do, score on single-mindedness. The three-year-old uses his brain not only to think but also to do tasks like seeing, hearing and running about, which need incredibly rapid and sophisticated electromechanical interactions we too run on electricity. However the computer just sits there and sends spacecraft to the moon or re-organizes the world banking system-which is very much easier. That's why man's dream of robot servants is still a long way off.

The dramatic growth of the world's population in the twentieth century has been on a scale without parallel in human history. Most of that growth has occurred since 1950 and is known as the population ''explosion''. Between 1950 and 1980 the world population increases from 2.5 to over 4 billion, and by the end of the century that figure will have risen to at least 6 billion. Growth of this size cannot continue indefinitely. Recent forecasts suggest that the total population will level-out at between 10 and 15 billion in the mid twenty-first century. Already there are encouraging signs that the rate of increase in several less developed countries is beginning to slow down.
