2)Hunting and collection.
4)Competition from human and animals.
1)Human exploit many natural habitats, destroying them in the process , e.g.Timbering destroys forests and endangers species like the orang-utan. Clearing of river banks destroys the natural habitat of the otter species every year.
2) Deforestation : Destruction of the forest leads to extinction of numerous species. It is estimated that deforestation of tropical rain forests has led to extinction of 6000 species every year .
1)Human hunt tigers for sport, crocodiles for their skins ,oryx as trophies, elephants for ivory, whales for oil and rhinoceros for their horn.
2)Some for the pet trade (e.g. tamarinds and parrots) and for research purpose,e.g. frogs.
These are in addition to the numerous species hunted for food .
Oil pollution threatens some rare species of sea birds. The build-up of certain insecticides along food chains endangers predatory birds like the peregrine falcon and the golden eagle.
It is, and always has been, part of the normal process of evolution that organisms which are genetically better adapted replace ones less well adapted.
1)Development of national parks and natural reserves.
2)Legal protection for endangered species.
3)Breeding in zoos and botanical gardens
4)Removal of animals from threatened areas
These are habitats legally safeguarded. They may preserve a vulnerable food source . In China areas of bamboo forest are protected to help conserve the panda. In Africa game parks help to conserve endangered species such as African elephant.
