Concerns over Pollution in Yucatan’s Underwater Caves
Mexico’s once pristine cenotes are becoming polluted due to a lack of water treatment plants in the region and an increasing population.
The underground river system that connects them is the only source of fresh water in the Yucatan Peninsula and environmentalists fear that if the government does not act, the pollution will bring about dire consequences.
Those polluted rivers also drain into the ocean, right into the Mesoamerican Barrier Reef, which further raises the concerns of environmentalists.
