- Norfolk - Siberian tigers (only 400 left in the world

- Social
- people become more educated and knowledge about the species increases
- increases public awareness of the importance of preserving biodiversity
- provide a key role in scientific research
- Economic
- can act as a tourist interest - income increase
- huge income gained - reinvseted for conservation
- Environmental
- helps protect species becoming extinct
- breeding programmes increase numbers
- have a positive impact on areas whee biodiversity has declined
- Social

- The advantages of ex situ - Breeding
- Scientists believe there could be just 45,000 wild orangutans left on the whole island of Borneo - a decline of 50% in the last 60 years
- main threat to orangutan's livse is the destruction of their habitat, the rainforest, by logging companies nd the establishment of oil palm plantations.
- 3 rehabilitated orangutans have been returned to the wild in Indonesia by the Borneo Orangutan Survival Foundation, from its rescue and reintroduction centre in East Kalimantan
- after spending most of their lives in human care the 3 orangutans were playing happily in the junge treetops - as nature intended
- airlifted from the Samboja Lestari Rescue and Reintroduction Centre ni the east of the island of Borneo to the Kehje Sewen forest to the south
- rare release of one of the world's most endangered primate species was made possible by funding provided by an internation group of fundraising partners
- including British charity, Orangutan Protection Foundation
