问题     Fifty years from now the world’s population will be declining. Unless people’s values change greatly, several centuries from now there could be fewer people living in the entire world than in the United States today. The big surprise of the past twenty years is that in not one country did birth rate(fertility) stop falling when it reached the replacement rate—2. 1 children per woman. In Italy, for example, the rate has fallen to 1. 2. In Western Europe as a whole and in Japan it is down to 1. 5. The evidence now indicates that within fifty years or so world population will peak at about eight billion before starting a fairly rapid decline.
    World population was growing by two percent a year in the 1960s. The rate is now down to one percent a year, and if the patterns of the past century don’t change radically, it will head into negative numbers. This view is coming to be widely accepted among population experts, even as the public continues to focus on the threat of uncontrolled population growth. [br] In the past twenty years the replacement rate has been falling in every country.
