The Republic of Maldives is a group of atolls in the Indian Ocean about 417 mi (671 km) southwest of Sri Lanka. Its 1,190 coral islets stretch over an area of 35,200 sq mi (90,000 sq km). With concerns over global warming and the shrinking of the polar ice caps, the Maldives is directly threatened, as none of its islands rises more than six feet above sea level.
