Cenotes are important for both historical and ecological reasons. Historically, cenotes were used as a source of water for the ancient Mayan civilization. From a modern ecological perspective, cenotes are vital freshwater habitats that provide refuge for species of aquatic flora and fauna, such as fish and turtles. In addition, these bodies of water also help to absorb carbon dioxide from the atmosphere and reduce climate variation in their immediate surroundings. Cenotes are a crucial component of Mexico's natural heritage and must be protected in order to safeguard their physical integrity and secure their stated historic value.

Cenotes are naturally occurring caverns located in the Yucatan Peninsula of Mexico and form when limestone bedrock collapses and exposes exposed groundwater underneath.

The Mayans believed cenotes were a gateway to the afterlife, as they venerated them and often made offerings at their edges.

The Yucatan Peninsula is estimated to have over 6,000 cenotes, some of which can reach depths over 100 meters deep making them popular for cave diving and snorkeling activities.

The crystal clear water from the cenote is emanating from the aquifer under the peninsula that stretches all the way down to Guatemala and Belize.

Pollution: Chemicals, sediment and other pollutants from human activities can enter cenotes, leading to water quality degradation.

Over-exploitation or recreation: Cenotes are becoming increasingly popular for recreational activities such as swimming, snorkeling and diving, often resulting in excessive use which can damage the environment and habitat of sacred spaces.

Climate change: Unpredictable weather conditions due to climate change could lead to water levels increasing or decreasing rapidly thus posing a risk to cenote habitats and ecosystems.

Invasive species: The introduction of invasive aquatic plant species by human activities can cause disruption to the delicate ecosystem located within the cenotes, leading to a decrease in native biodiversity and disruption of natural processes and dynamics.
