According to people in the know, the current global population of 7.3 billion is forecast to reach 9.7 billion in 2050 and 11.2 billion in 2100, slightly above the last set of U.N. projections. Well, projections are just that, more or less.
Anyone surprised that most growth will happen in developing regions, particularly Africa, according to the report World Population Prospects?
Right now, people by the tens of thousands are leaving, escaping many places where the impact of the predicted population growth will be unavoidable, at least based on the present situation.
Up to now only two countries have implemented child limits with minimal success, and those are China and Vietnam. Many other nations could also gain from a one or two child family planning policy, but they lack the prevision or political impetus to make it happen.
