This book is concerned with near-field measurements and in this chapter, we would like to set the context of why this is necessary from a human point-of-view and introduce the field magnitudes that are important. The degradation of the natural electromagnetic environment is the forgotten price that must be paid for our inconsiderate enthusiasm for industrial revolution. As a result, we are reaching a situation in which spending for the protection of the environment must sometimes exceed the investment in the systems causing the degradation.
