Our wants for food, housing, medicine, transportation, luxuries, and all the other benefits of industrialization have resulted in the exploitation of our natural surroundings. We know our actions affect the physical world we depend on, so why must we be faced with catastrophic problems--overpopulation, the loss of bio-diversity, global warming, and the like--before we act to protect the planet's ecosystem--and then often inadequately?
With astute analysis Peter Seidel explores the complex convergence of psychological, social, economic, and political factors that keep us from acting in our own self-interest. An environmental and human relations visionary, Seidel proposes adoption of a new "world model," a "universal ethic," and long-term societal goals.
Educators and journalists must give us a better understanding of ourselves-creatures evolved to function in a hunter-gatherer society, not in the complex, hazardous world we have created. We must learn to use our minds to control our primitive drives rather than to satisfy them.

This book is a result of the lectures and discussions during the conference "Theory and Practice of Geometric Modeling". The event has been organized by the Wilhelm-Schickard-Institut fiir Informatik, Universitat Tiibingen and took place at the Heinrich-Fabri-Institut in Blaubeuren from October 3 to 7, 1988. The conference brought together leading experts from academic and industrial research institutions, CAD system developers and experien ced users to exchange their ideas and to discuss new concepts and future directions in geometric modeling. The main intention has been to bridge the gap between theoretical results, performance of existing CAD systems and the real problems of users. The contents is structured in five parts: A Algorithmic Aspects B Surface Intersection, Blending, Ray Tracing C Geometric Tools D Different Representation Schemes in Solid Modeling E Product Modeling in High Level Specifications The material presented in this book reflects the current state of the art in geometric modeling and should therefore be of interest not only to university and industry researchers, but also to system developers and practitioners who wish to keep up to date on recent advances and new concepts in this rapidly expanding field. The editors express their sincere appreciation to the contributing authors, and to the members of the program committee, W. Boehm, J. Hoschek, A. Massabo, H. Nowacki, M. Pratt, J. Rossignac, T. Sederberg and W. Tiller, for their close cooperation and their time and effort that made the conference and this book a success.

Global warming, environmental degradation, the rapid pace of technological innovation, and the economic stresses of globalization give rise to much speculation about the future. How will these dynamic factors affect society in the coming decades? In this dystopian novel, environmental expert Peter Seidel has created a stark and haunting vision of a world on the near horizon.
Carl is a small-town midwestern businessman who is accidentally put into a coma when he receives an inadequately tested vaccine. When he finally regains consciousness, he discovers that it is the year 2045 and his unusual medical story and recovery have turned him into an international celebrity. As he visits family and friends, he finds out that almost everything has gone wrong and the family business he ran thirty-five years ago has disappeared. Carl's fame lands him a job on a seemingly idyllic tropical island with one of the eight giant international corporations that own almost everything. His job is to help promote a soft drink. He is overwhelmed by the unbounded luxury he finds on the island. But he learns that the ethical standards in this strange place are only a front. During a business trip, he discovers something that horrifies him and turns him in a new direction, one beset with life-threatening dangers.
Seidel skillfully projects a wide range of current trends into a believable and disturbing near-term future scenario.
