Raul Padilla, member of the Jaguar Wildlife Center which works to protect jaguars, poses for a portrait inside a miles-long cave system known as "Garra de Jaguar," or The Paw of the Jaguar," underneath the planned route of the Maya Train in Playa del Carmen, Quintana Roo state, Mexico, Thursday, Aug. 4, 2022. Mexican President Andres Manuel Lopez Obrador wants to finish the entire train in 16 months by filling the caves with cement or sinking concrete columns through the caverns - the only places that allowed humans to survive in this area.
