Questions 1-9In 1972, a century after the first national park in the United States was established atYellowstone, legislation was passed to create the National Marine Sanctuaries Program.The intent of this legislation was to provide protection to selected coastal habitats similarTo that existing for land areas designated as national parks. The designation of an areas5)a marine sanctuary indicates that it is a protected area, just as a national park is. Peopleare permitted to visit and observe there, but living organisms and their environments maynot be harmed or removed.The National Marine Sanctuaries Program is administered by the National Oceanicand Atmospheric Administration, a branch of the United States Department of Commerce.10)Initially, 70 sites were proposed as candidates for sanctuary status. Two and a half decadeslater, only fifteen sanctuaries had been designated, with half of these established after1978. They range in size from the very small (less than I square kilometer) Fagatele BayNational Marine Sanctuary in American Samoa to the Monterey Bay National MarineSanctuary in California, extending over 15,744 square kilometers.15) The National Marine Sanctuaries Program is a crucial part of new managementpractices in which whole communities of species, and not just individual species, areoffered some degree of protection from habitat degradation and overexploitation. Onlyin this way can a reasonable degree of marine species diversity be maintained in a settingthat also maintains the natural interrelationships that exist among these species.20) Several other types of marine protected areas exist in the United States and othercountries. The National Estuarine Research Reserve System, managed by the UnitedStates government, includes 23 designated and protected estuaries. Outside the UnitedStates, marine protected-area programs exist as marine parks, reserves, and preserves.Over 100 designated areas exist around the periphery of the Carbbean Sea. Others range25)from the well-known Australian Great Barrer Reef Marine Park to lesser-known parksin countries such as Thailand and Indonesia, where tourism is placing growing pressureson fragile coral reef systems. As state, national, and international agencies come torecognize the importance of conserving marine biodiversity, marine projected areas.whether as sanctuaries, parks, or estuarine reserves, will play an increasingly importantrole in preserving that diversity.
