The vaquita, a critically endangered porpoise in Mexico's Sea of Cortez, faces extinction with less than a dozen remaining. Illegal net fishing for totoaba, driven by high demand for its swim bladder in China and Mexican organized crime, threatens the vaquita. Conservation efforts have led to conflict in Baja California's fishing communities, reliant on illicit totoaba income. A New Year's Eve 2020 incident resulted in a fisherman's death and another's injury during a clash with an NGO ship enforcing net bans. Linda Pressly reports on the complex situation and the challenges in saving the vaquita.
