Many plant and animal species are on the verge of their extinction because of loss of forest land by indiscriminate use by humans. As a biology student what method would you suggest along with its advantage that can protect such threatened species from getting extinct.
New species entering the geographical region are known as alien species. Introduction of alien species causes a significant loss to the biological community. However, some of the species are able to establish the area. Such successful exotic species eliminate the native species to the point of extinction, and so alter the habitat that many native species are no longer able to persist.
For example introduction of Nile perch into Lake Victoria disturbed the ecosystem of the lake by eliminating several native species of small cichlid fishes.
The destruction of natural habitat is the primary threat to biodiversity. When the natural habitats are diminished then the flora and fauna have no place to survive and thrive and it will lead to the extinction.
