Sustainability is an important concept that is widely referenced and that has achieved broad support. Yet it remains inherently difficult to implement because of its complexity and due to the enormous shifts in thinking that it proposes. Particularly challenging is the development and implementation of technology, the vast majority of which has significant potential negative consequences for the health of both people and planet. This book provides natural and social scientists, engineers, architects, builders and other technical professionals with a clear description of the meaning of sustainability and a practical guide to the ethical challenges involved in its promotion and achievement. It describes the ethical concepts and principles that are inherent in sustainability and is designed to aid these professions in evaluating and directing their activities, particularly when developing, deploying, and employing technology. Sustainability is commonly understood to require the balanced pursuit of three goods: ecological health, social equity, and economic welfare. It is grounded on the ethical commitment to the well-being not only of contemporary populations but also the wellbeing and enhanced opportunities of future generations. The scientific and technical professions have a special responsibility in this regard because the knowledge and technologies they develop and employ have immense impacts on natural environments, economies, and the empowerment of citizens and societies. Moreover, their efforts and achievements can continue to produce effects, for good or ill, well into the future. In articulating the challenge of pursuing both intergenerational and intragenerational benefits for environments, societies and economies, this book grounds practical decision making in ethical concepts and values. Through exposure to a wide variety of concrete examples, case studies, moral debates, and exercises, readers will gain a nuanced understanding of the ethics of sustainability and develop a set of practical decision skills that may be employed in its pursuit. The book engages a broad range of applications such as nuclear and solar energy systems, biotechnology and genetic engineering, materials extraction, design and production, built environment design and construction, information technology and robotics, nanotechnology and communications technology, agricultural and forestry technologies. While addressing large-scale national and global issues such as climate change, higher energy costs, water and food shortage, poverty, species extinction, and resource depletion, The Ethics of Sustainability also brings home the personal impact scientists and technical professionals can have at the workplace, in their communities, and in their homes.
