Massive coral bleaching episodes have impacted the function of the reefs and increased rates of mortality. Coral reefs support over one million plant and animal species and their economic value is pro¬jected to more than US $ 30 billion annually. Extreme climatic con¬ditions, however, are most likely to increase in the future with cur¬rent climate scenarios. Projected increases in carbon dioxide and temperature exceed the conditions under which coral reefs have flourished over the past 500 000 years. Coral reefs are crucial bio¬diversity hotspots and support both coastal fisheries and tourism in many regions. Coral reefs, however, are in decline in many regions as a result of numerous pressures, including, but not limited to, extreme climate events, unsustainable fishing practices, diseases, sedimentation, and discharge of untreated sewage. Increasing re¬silience and securing rapid recovery of coral reefs will be essen¬tial for the ability of these ecosystems to support coastal fisheries and coastal livelihoods and cultures in the future. However, this resilience and recovery may be seriously impounded by unsustain¬able coastal infrastructure development and marine pollution from land-based sources. At the current rate of growth, coastal develop¬ment may impact up to 90% of the tropical and temperate coast¬lines by 2032 if development continues unchecked. While progress has been made to reduce the discharge and impacts of oil spills and persistent organic pollutants (POP’s), there now needs to be a focus on the largest current threats to the coastal marine environment : untreated sewage and piecemeal coastal development.

The Territory of American Samoa lies roughly 14 degrees south of the equator between longitude 169 and 173 west and about 2,500 miles southwest of Hawaii. The principal islands are Tutuila, Aunu'u, and the Manu'a islands (a cluster of three islands, Ta'u, Ofu and Olosega, located about 65 miles east of Tutuila). Swains Island, a small island with a population of less than 25 and Rose Atoll, an uninhabited atoll about 120 miles east of Tutuila make up the remainder of the territory. The population of the territory was 57,291 people in the year 2000, of which approximately 97% live on the island of Tutuila. The islands of American Samoa are volcanic in origin and exhibit the rugged topographic relief common to the Pacific volcanic islands. The climate of the territory is tropical, with uniform high temperatures and high humidity throughout the year. Mean daily temperature during the year varies from about 78 to 82 degrees Fahrenheit. The maximum altitude is about 3,180 ft. above mean sea level at the summit of Lata Mountain on Ta'u Island. Tutuila, with an area of 53 square miles, is the largest island in the territory. It is approximately 20 miles long and ranges in width from less than one mile, to a maximum of 5 miles at the Tafuna Leone plain. A sharp-crested ridge 1,000 to 2,000 feet high with steeply eroded slopes dominates the entire length of the island.
