Mangrove forests occur extensively in the tropic areas rich in wildlife and other nonforestry resources and provide a wide array of raw materials for livelihood and production processes and have been a major source of income generation and subsistence for the local people.Exploitation of timber, fuel wood, poles, industrial raw material, and many other non-wood products from the mangrove forests give rise to large scale economic activity and income generation. At present, mangrove forests are facing great peril. Reckless exploitation and swampland reclamation result in their gradual degradation. This article deals with the world‘s mangrove forest resources and their benefit to people ; describes the cmrrent status, points out the main causes of the destruction of these forests, presents proposals for protecting mangrove forests, and discusses international cooperation in protecting the world‘s mangrove forests. 相似文献
