Here is a interesting article relating to Linnean taxonomic systems and DNA evidence. The economist suggests that over eager taxonomists are over inflating the number of new species for the benefit of conservation. Does this provide evidence of scientists and bias? worth reading to consider how economists and biologist clash. (See Here)
I don't think this article is addressing the main issues associated with biodiversity. The entire reason we protect endangered species is to protect ecosystems. This article argues that the polar bear isn't a unique species; regardless of the validity of that statement, they are integral to the polar ecosystems which they inhabit. The classification of species or subspecies should have nothing to do with their protection.
