A proposed immigrant detention center in the Everglades dubbed "Alligator Alcatraz" is drawing criticism for its potential effect on the ecosystem.

Florida this week started construction on a migrant detention facility the state is billing as “efficient” and “low-cost” – because Mother Nature will provide much of the security.

Called "Alligator Alcatraz" by state officials, Gov. Ron DeSantis said Thursday during a stop in Boca Raton that the facility will have "zero impact" on the Everglades.
