Although the term "karst" is not widely known, nearly 25% of the world's population lives in karst areas. Living With Karst, the 4th book in the AGI Environmental Awareness Series vividly illustrates what karst is and why karst areas are important. The booklet also discusses karst-related environmental and engineering concerns, guidelines for living with karst, and sources of additional information.
