In Europe and elsewhere, industrial, technological and economic development has created wealth and opportunity. Health has largely benefited: many people in Europe, although unfortunately not all, live longer and better than ever before. These positive trends must be sustained and extended to as many people as possible. Technological development has often outpaced scientific knowledge related to the determinants of health. Increasing complexity in societal organization multiplies the pathways by which a variety of agents can affect health, including physical risk factors such as toxic chemicals or radiation, social circumstances such as exclusion and deprivation, limited access to clean natural resources, and the endless combinations of them all. Decisions taken in domains apparently distant from health often have the potential to affect people’s health positively or negatively because of the great number of connections and exchanges in modern life. Health is a function of highly complex systems, which can be unintentionally disrupted in unpredictable ways and result in adverse health consequences that may be serious and irreversible. When solid science is available, health can be protected effectively through preventive action. However, people must humbly acknowledge that science has limitations in dealing with the complexity of the real world and do their utmost to promote the development and progress of science. While people strive for better science, how can health be protected? In particular, how can people ensure that children and future generations will have the opportunity that many people have of reaping the benefits of progress and enjoying good health? This question is difficult. Irreparable
