The Maldives is an archipelagic state in South Asia, situated in the Indian Ocean. It is composed of 26 atolls, which are ring-shaped coral reefs that encircle a lagoon, partially or completely. The capital is Malé. The Maldives is the world's lowest country, with an average ground-level elevation of just 1.5 meters above sea level. Its highest natural point is only 2.4 meters, making it extremely vulnerable to rising sea levels. The islands are entirely made of coral and are protected by a complex system of reefs that act as a barrier against waves. The economy is heavily reliant on high-end tourism and fishing. Its crystal-clear waters are home to a vast array of marine life, including whale sharks and manta rays.
