Sarawak features vast areas of both lowland and highland rainforest. However, Sarawak has been hit hard by the logging industry and the expansion of monoculture tree plantations and oil palm plantations.Sarawak can be divided into three natural regions. The coastal region is rather low lying flat country with large extents of swamps and other wet environments. The hill region provides most of the easily inhabited land. Most of the larger cities and towns have been built in this region. As the swamps make up much of the coast, the ports of Kuching and Sibu have been built some distance from the coast on rivers, while Bintulu and Miri are close to the coast at the only places that the hills stretch right to the China Sea. The third region is the mountain region along the border and with the Kelabit and Murut highlands in the north.
Sarawak has more than 40 sub-ethnic groups, each with its own distinct language, culture and lifestyle. Cities and larger towns are populated predominantly by Malays, Melanaus, Chinese, and a smaller percentage of Ibans and Bidayuhs who have migrated from their home-villages for employment reasons.
