Using text, graphics, satellite imagery, and data this publication with accompanying teacher's guide seeks to illustrate three main points concerning world population: (1) rapid world population growth is placing untenable immigration pressures on the United States; (2) immigration and U.S. population growth patterns generally are regionally concentrated, especially in coastal counties; and (3) given population and natural resource/environmental pressures, there are now profound and urgent reasons to address immigration within a broader national population policy framework. The text is suitable for use in high school, junior college, and college-level social science classes and applies and employs an interdisciplinary approach. The book is divided into three main sections. Part I contains eight complex graphs and map graphs displaying international data about world population growth. Part II contains six complex graphs and map graphs and six satellite photographs displaying the effects of population growth on the natural resources and environment of the United States. The third part, the Appendix, contains 18 statistical tables. Three short essays by Dan Stein, Garrett Hardin and Richard D. Lamm, present the ideological argument of the book. The teacher's guide contains five lesson plans and sample examination questions. (LZ)
