The Director of the Madidi Park, Marcos Uzquiano, is a determined ranger who deems his service to this kind of preservation work a “calling.” In particular, Marcos is resolute in tracking down the illicit jaguar trade that has been pervasive in Bolivia, and disrupting this unrelenting eradication of an entire species.
