Species are disappearing from the earth at a rate of hundreds, and perhaps thousands, of times greater than every before witnessed. According to many scientists, this rapid destruction will lead to irreversible changes in the earth’s ecosystem. The Expendable Future provides a comprehensive and critical evaluation of the politics of biological diversity in the United States and of state and federal policies on endangered species from the early 1960s to the present. Drawing on congressional hearing and debates, previously unpublished public opinion surveys, interviews with state officials and employees of the Department of the Interior, and internal documents from this and other government agencies, Tobin provides an in-depth analysis of the policies on endangered species and the policy relationships among the different units of government involved in implementation. He examines the resources that are available for the protection of endangered species and the way in which those resources are matched to the priorities. Tobin also discusses the processes by which species are classified as endangered, how these species’ critical habitats are determined and protected, and the successes, and mostly failures, of current recovery programs.

Dr. James Canton, a renowned futurist, CEO of the Institute for Global Futures, and Fortune 1000 advisor, charts a course to steer you through the volatile changes that lie 5, 10, and 20 years ahead. The Extreme Future is this generation’s Future Shock, Alvin Toffler’s classic book on what’s next and how to prepare for tomorrow. Get ready for fast, radical and complex change. Get ready for the Extreme Future. Our world is constantly buffeted by new and dramatic changes that we can’t fully grasp. No one is fully prepared for the challenges, crises and risks that lie ahead. The Extreme Future is a blueprint for what’s next and how to navigate these changes. An advisor to three White House’s spanning more than 30 years, Dr. Canton challenges us that with the right information about future trends it is possible to identify probable outcomes. It is possible, with the right information to navigate the Extreme Future. The book covers the following major trends: How climate change and energy trends will reshape the planet How shifting population trends will transform the workforce How radical innovation trends will competitively drive business How astounding medicine trends will enhance people’s life How dangerous terrorism trends will threaten the individual. How the rise of China will bring on a new global power struggle The answers to these questions are not only available, but contained within these pages. The Extreme Future is the forecasting handbook for the twenty-first century.

Loss of Biodiversity introduces readers to the important concepts for understanding the environmental challenges and consequences of the declining diversity of life on the planet. Contributions from scientists, and academics in the social sciences and humanities provide readers with an initial "tool kit" for understanding the concepts central to their disciplinary perspective and the multi-dimensional aspects of the loss of biodiversity.

This study has the objective of identifying missions for future orbit transfer vehicles (1995-2010) and defining the technology, operations and vehicle concepts that satisfy the transportation requirements. Several issues were examined. The first involved comparison of reusable space and ground based LO2/LH2 OTV's. Both vehicles used advanced space engines and aero assist capability. The SB OTV provided advantages in life cycle cost, performance and potential for improvement. The second issue was the comparison of an all LO2/LH2 OTV fleet with a fleet of LO2/LH2 OTVs and electric OTV's. The normal growth technology electric OTV used silicon cells with heavy shielding and argon ion thrusters. In this case, the LO2/LH2 OTV fleet provided a 23% advantage in total transportation cost. The third issue dealt with the impact of accelerated technology. An accelerated technology LF2/LH2 OTV provided improvements in performance relative to LO2/LH2 OTV but had higher DDT & E cost which negated its cost effectiveness. The accelerated technology electric vehicle used GaAs cells and annealing but still did not result in the mixed fleet being any cheaper than an all LO2/LH2 OTV fleet. The study conclusion is that reusable LO2/LH2 OTV's can serve all general purpose cargo roles between LEO and GEO for the foreseeable future. The most significant technology for the second generation vehicle would be space debris protection, on-orbit propellant storage and transfer and on-orbit maintenance capability.
