Risks seem to abound in our everyday lives, especially the risks flowing from the explosion of our modern technology, with its pesticides, pollution, nuclear power, microwave radiation and chemical trace elements in food of all kinds. Two questions face all of us: how real are these risks and, if real, how do we manage our lives in order to avoid personal damage from them? The book examines these questions, delving into the nature and true seriousness of risk (as opposed to how bad the risk seems to be), into how we measure risk and how we regulate it. Lewis includes the latest scientific information on carcinogens and the greenhouse effect as well as detailed discussion of road safety, the risk of air travel, nuclear power and acid rain.
