Amongst philosophers desirous about biodiversity, Santana is thought for advancing an eliminativist argument about biodiversity. Principally, Santana thinks that the idea of biodiversity is ineffective for prediction and clarification in conservation science and, consequently, that we should always eliminate it. I don’t suppose Santana is true about this, however he makes a priceless level that I’ll construct upon right here.
Santana’s suggestion is that conservation scientists swap out the biodiversity idea for one thing extra readily measurable, akin to what these scientists intention to protect (for instance, taxonomic richness or ecosystem providers). Santana calls these “organic values,” which makes specific the normative issues embedded in conservation science. Now, take an ecosystem service that may be quantified, akin to the worth of pollinators in a sure space of the world. To speak a couple of “disaster” in that little bit of nature, you don’t want to match your worth to some deep-past measurement. You’ll be able to set a threshold based mostly on different issues and, when that threshold is breached, you might be justified in taking motion. This might work for different organic values, too, like species richness in a biodiversity hotspot or tree density within the Amazon. Anyway, it supplies a principled approach of speaking concerning the current disaster that doesn’t hinge on problematic comparisons between the current and the previous.
So, to sum up: I’ve argued that justifying the declare that we’re in a biodiversity disaster by evaluating measures of the present standing of biodiversity to paleodiversity is problematic as a result of the 2 measurements are incommensurable: they use information that’s not simply in contrast they usually conceptualize the focal phenomenon in a different way. But when we change discuss of “biodiversity” with “organic values,” we will purpose concerning the severity of the current disaster with out downplaying its significance, and with out counting on inferences based mostly on 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!]
