As a comprehensive regional analysis for future conservation and development, this plan examines in detail the alternatives faced by Californians today--and, by implication, throughout the nation and the world. It demonstrates how a broad-scale, systematic approach to solving our major environmental, social, and economic problems can be made, focusing on the interconnections between problems to identify underlying causes of the physical and psychological disruption of our lives on the land. It contrasts the inadequacy of current, fragmented, single-purpose methods of handling problems with the potential value of a unified program of goals and driving policies. The plan identifies two prototypes, called "California One" and "California Two." The first is a picture of the kind of California that will come to pass if the traditional way of solving problems continues into the future. The second is a proposal for an alternative way of solving problems, an outline of what government and private enterprise would have to do to carry out this alternative, and a view of what life might be like in "California Two." Through comparisons and projections to the year 2000, it explores the implications of alternative futures for California. Numerous charts and diagrams are presented throughout the work. (BL)
