 Thus, there are many different types of diversity encoded in the sorts of true surrogates we would like to conserve and they do not positively correlate in straightforward ways. If this is right, Santana contends that the concept of biodiversity in effect is not tracking a feature of the biological world. At most it is a placeholder for whatever conservation biologists choose to conserve. The concept has certainly made its way into public discourse and one might worry that this would be extremely disruptive if we removed it from conservation practice. However, Santana suggests we should not try to decide what to conserve based on some elusive property of biological systems, which really is just a disjunction of very different diversities. Rather, the tools through which value conflicts are best articulated is from political science and economics (Colyvan, Justus, &amp; Regan 2011; Frank &amp; Sarkar 2010). Regardless of the tools used, Santana argues that we should bypass the concept of biodiversity and consider the biological values that we share and evaluate true surrogates on those grounds.
