Scene on one of more than 2,000 islands that make up the Trust Territory of the Pacific, better known as Micronesia. Despite the idyllic tropical setting (much of the territory is within a few degrees of the Equator, covering some 3 million miles of ocean), there are problems: a critical shortage of qualified teachers and too few classrooms, bad roads and inadequate medical facilities. The Peace Corps has been invited by the United Nations to set up programs in education, health, and public works to aid the nearly 100,000 citizens of Micronesia.
