“Modernisation” has often come at a terrible cost to public health, safety, and the environment. For example, technology has made it possible to cut forests faster and to pollute virtually all corners of the earth. In this interdisciplinary course, students will learn how technology can be used to improve public health, safety and environment while retaining profit as the driving force for further development. Much attention is on the societal perceptions and concerns (including myths) about environmental, health and safety impact of various technologies, including nuclear energy generation and alternative green fuels. Healthy and safe living habits will be discussed as well.
