Biodiversity refers to the variety of life in n area which is usually measured as the number of species that live in an area. Loss of biodiversity is the main problem of the wide destruction of natural habitat, especially in tropical rainforests. In fact, IUCN reported that 73% of the extinct, endangered, vulnerable and rare species were concerned by habitat destruction. Biodiversity is a crucial natural resource, and the threatened species could provide important crops, fibers, and medicines. Areas with high biodiversity should not be converted into industrial or agricultural sites to prevent loss of biodiversity.
