The world is a big place. Its population increases fantastically. By the end of the century six thousand million people will be living in the five continents, though the greatest number by far will be living in Asia. In forty years’ time communications will have been improved so that even the most remote areas will be within access. Illiteracy will have been largely conquered. Public health will have made great strides. Independence and freedom from external control will be the lot of every nation.
