A group of Mexican singers, actors and environmentalists have issued a public protest against plans to cut down a swath of low jungle between Cancun and Tulum to build a tourist train line.

In a series of videos, more than a dozen celebrities ask President Andrés Manuel López Obrador to stop the project, which requires massive tree cutting and threatens to collapse underground caves known as “cenotes.”

On Tuesday, actors like Eugenio Derbez and Kate del Castillo, and singers like Natalia Lafourcade, published a video asking the president to stop the construction.
