Scientific evidence is mounting concerning rapid population growth in the United States that is causing the deterioration of life supporting environmental resources (Bartlett and Lytwak, 1995; Grant, 2000, 2003; Pimentel and Pimentel, 2003; Sachs, 2004). Genuine concerns are expressed about future food security, prosperity, quality of human life, and maintaining the personal freedoms Americans now enjoy. The indisputable facts associated with population growth are that more people will require food as well as pure water, energy, and land for all their activities, including urbanization and highways.
Yet as the U.S. population speeds ahead with 3.3 million added people each year, severe soil erosion on croplands continues and further diminishes soil productivity. Fresh water resources even now experience heavy over-use, and conflicts are intensifying, especially between the public and agriculture. Taken for granted are the mostly imported oil and natural gas that power U.S. cars, agriculture, and many other aspects of American life.
