An anti-pollution tract that emphasizes damage to coastal regions, particularly in the Massachusetts area. Effects of weather and erosion are covered, as well as changes resulting from increased numbers of shoreline homes and people-produced pollutants. The greenhouse effect, which may change the ocean level, is also mentioned. Young people are encouraged to join organizations committed to safeguarding the coast. Research here, however, seems incomplete; mentioning the Chesapeake Bay and Puget Sound does not mask the fact that the examples and facts come primarily from Massachusetts sources. Also possibly as a result of the collaborative authors preparing different sections, style is uneven. The distinct ion made between evolutionary changes (which the authors feel must be accepted) and cataclysmic ones is murky. Though this provides a preliminary view of coastal problems, the topic deserves more complete coverage.
