LIMITS TO GROWTH: The 30-Year Update

Updated for the second time since 1992, this book, by a trio of professors and systems analysts, offers a pessimistic view of the natural resources available for the world's population. Using extensive computer models based on population, food production, pollution and other data, the authors demonstrate why the world is in a potentially dangerous "overshoot" situation. Put simply, overshoot means people have been steadily using up more of the Earth's resources without replenishing its supplies. The consequences, according to the authors, may be catastrophic: "We... believe that if a profound correction is not made soon, a crash of some sort is certain. And it will occur within the lifetimes of many who are alive today." After explaining overshoot, the book discusses population and industrial growth, the limits on available resources, pollution, technology and, importantly, ways to avoid overshoot. The authors do an excellent job of summarizing their extensive research with clear writing and helpful charts illustrating trends in food consumption, population increases, grain production, etc., in a serious tome likely to appeal to environmentalists, government employees and public policy experts.
