Debate Over Biodiversity Hotspots

Some conservationists have argued that biodiversity conservation resources should be targeted towards “hotspots” – areas where species' diversity is greater than normal. Others have argued for a different focus, such as upon areas faced with imminent destruction, large intact ecosystems, and even not prioritizing at all given that all land benefits from conservation. Here is a good article regarding a new study which add credence to these contrarians. A primary concern that I have and have enunciated over the years is the detachment between the amount of natural habitat required for global ecological sustainability, versus the relatively unambitious targets in terms of extent of habitats to be maintained under a hotspot approach. I do not believe the hotspot approach is sufficient to maintain either species or ecosystems, nor the integrity of the global biosphere.
