One of the major challenges of our time is the management of risks emanating from modern technologies. Yet as diverse as these technologies are, ranging from nuclear power generation over genetically modified organisms to nanotechnology and many more, as different are the risk management and regulation strategies offered to cope with their potential risks. This book is therefore dedicated to one of these strategies, the Precautionary Principle. The book offers a general model for the implementation of the Precautionary Principle for risk regulation. At the same time, the book integrates various scientific approaches towards the Precautionary Principle, such as the social sciences, natural sciences and law.
