The world’s human population is currently more than 5.6 billion, projected to reach nearly 8.4 billion by the year 2025 and may reach a disastrous 15 billion by 2100 (PCC 1989). Presently a quarter million humans are added each day. Many leading scientists and public organizations are concerned about the rapid growth in population numbers and the deterioration of natural resources and the environment caused by human numbers and activities (CEQ 1980, Keyfitz 1984, Hardin 1986, Demeny 1986, Ehrlich and Ehrlich 1990, Holdren 1992). As populations and their consumerism increase basic resources are depleted, this leads to environmental degradation while freedom of individual choice and quality of life decline (Durning 1989, Durham 1992). At present, from 1.2 billion (Durning 1989) to 2 billion people (Abernethy, Vanderbilt University, PC, 1992) worldwide are living in poverty, malnourished, diseased, and experiencing short life-spans. In the United States 36 million now are living in poverty (USBC 1994).
