Amongst philosophers taken with biodiversity, Santana is understood for advancing an eliminativist argument about biodiversity. Principally, Santana thinks that the concept that of biodiversity is unnecessary for prediction and rationalization in conservation science and, as a result, that we must eliminate it. I don’t suppose Santana is true about this, however he makes a precious level that I can construct upon right here.
Santana’s advice is that conservation scientists change out the biodiversity idea for one thing extra readily measurable, akin to what those scientists purpose to maintain (for instance, taxonomic richness or ecosystem products and services). Santana calls those “organic values,” which makes specific the normative concerns embedded in conservation science. Now, take an ecosystem provider that may be quantified, akin to the worth of pollinators in a undeniable space of the sector. To speak about a “disaster” in that little bit of nature, you don’t want to examine your price to a couple deep-past size. You’ll be able to set a threshold in line with different concerns and, when that threshold is breached, you might be justified in taking motion. This is able to paintings for different organic values, too, like species richness in a biodiversity hotspot or tree density within the Amazon. Anyway, it supplies a principled method of speaking in regards to the provide disaster that doesn’t hinge on problematic comparisons between the existing and the beyond.
So, to sum up: I’ve argued that justifying the declare that we’re in a biodiversity disaster via evaluating measures of the present standing of biodiversity to paleodiversity is problematic for the reason that two measurements are incommensurable: they use information that’s not simply in comparison and so they conceptualize the focal phenomenon otherwise. But when we substitute communicate of “biodiversity” with “organic values,” we will reason why in regards to the severity of the current disaster with out downplaying its significance, and with out depending on inferences in line with problematic comparisons.*
[* You might still have questions about another narrative that captures the taxonomic loss are experiencing today, that of the “sixth mass extinction.” We often hear that the world has entered a sixth mass extinction that is comparable to the “Big Five” identified by Raup and Sepkoski. If you are interested in how a mass extinction is defined and how hard it is to comparatively measure today’s rates of species loss, I recommend that you check out my co-authored paper “Are we in a sixth mass extinction? The challenges of answering and the value of asking,” which is forthcoming in The British Journal for Philosophy of Science!]
