The atolls and islands are situated in two almost parallel chain-like formations known as the Ratak (Sunrise) group and Ralik (Sunset) group. The total number of islands and islets in the whole Republic is approximately 1,225 spreading across a sea area of over 750,000 square miles. The total land area is about 70 square miles (181 square kilometers). The mean height of the land is about 7 feet above sea level (2 meters).
The people of the Marshalls share with all the people of the Pacific a deep and abiding respect for the land and the sea, elements which have provided them daily sustenance for thousands of years. This fragile natural environment has been well-tended in customary practice, providing a basis for subsistence living and for social, economic and cultural well-being. The RMI now faces threats to this natural resource base, including rapidly increasing population, rising material expectations, demands for economic growth and the depletion or degradation of natural resources.
