Sumatra Island

Sumatra is the largest island in Indonesia, spanning a diagonal northwest-southeast axis, and is the sixth-largest island in the world with an area of 482,286.55 km2. The island is bordered by the Indian Ocean to the northwest, west, and southwest, and is separated from the Malay Peninsula by the Strait of Malacca and from Java by the Sunda Strait. Sumatra has a diverse geography, with the Bukit Barisan mountains forming the backbone of the island and large plains and lowlands in the northeastern area. The island has a wide range of plant and animal species, but has lost almost 50% of its tropical rainforest in the last 35 years, resulting in serious environmental damage and the endangerment of many species.learn more on wikipedia
