| 內容簡介 | The world's population has increased fourfold since 1900. If current growth rates continue, it will double again before the year 2030. Yet, the earth's resources are finite and we are already testing its limits. World Population is an excellent discussion starter on the population issue.
This program is a striking depiction of actual population growth from 1 A.D. to the present and of projected future growth to the year 2020. As the years roll by on a digital clock, dots appear on a world map representing millions of people added to the population. References to historic events also appear, helping place population changes in context. The visual presentation makes statistical information exciting and easily understood.
