Introduction Chapter VII:
Biodiversity Hotspot and Conservation Priorities
Despite that biodiversity losses are occurring everywhere on
Earth, some areas which are both extraordinarily rich in life forms and particularly threatened from a number of sources have been identified.
The principal behind the concept of biodiversity hotspot comes from the fact that despite that all ecosystems on
Earth should be preserved, only limited funds are available worldwide to undertake such needed actions.
As a general trend, equatorial and tropical zones have a particularly rich biodiversity when compared to the rest of the word. The colder it gets, the less bio-diverse the ecosystems tend to be.
As such, it is necessary, in order to preserve as much biodiversity as possible, to focus on areas which are the most at risk and where the efforts will result in the greatest number of species saved.
Examples of biodiversity hotspots include the rainforest of
Borneo and as a matter of fact most of the forests of
Indonesia and Malaysia, Reef environments across tropical zones and many others.
Often, loss of biodiversity arise from rapid deterioration of the environment in the pursue of the extraction of resources for immediate profit. One must however understand that such models are not sustainable.
18 principal biodiversity hotspots where conservation should be prioritized have been identified.
