Such efforts have not fully accounted for the Earth's fundamental interconnectedness and unity; as a result, pollution control has often lagged behind pollution-related problems. This book puts all the pieces together as it explains how pollution affects all components of the environment. Using layperson's language and an easy-to-use question and answer format, it describes: how the components of the environment operate together; major sources of pollution; and what we can do to clean up our surface water, groundwater, and air. Care has been taken to avoid bias and to present only the most sound, objective data available.
