With extinction rates 1000–10,000 times greater than natural, ex situ and in situ conservation programmes need additional support to save species.
For many animals, dwindling numbers are becoming fragmented populations with low genetic diversity, threatening long-term species viability. However, anthropogenic activities are causing the sixth mass extinction, threatening even our own species. Biodiversity is defined as the presence of a variety of living organisms on the Earth that is essential for human survival.
