Construction worker Oscar Uc-Pool operates machinery at the construction site of section 2 of the new Mayan Train route near the town of Santa Rosa, in Tenabo, Campeche, Mexico, May 17, 2022. In the eyes of President Andres Manuel Lopez Obrador, the railway his government is building - known as the Tren Maya - will bring modern connectivity to areas for generations deprived of significant economic benefits. But pristine wilderness and ancient cave systems beneath the jungle floor are critically endangered by the railway and its hasty construction, droves of scientists and environmental activists say.
