The specialist warned that regardless of the effects on the tourism sector, the arrival of sargassum to the coasts of the peninsula would affect the reproduction of sea turtles that migrate to these Mexican beaches to nest, because they cannot cross the sargasso barrier to spawn in the sand.

“And in the case that the adult female turtles are able to get to the beaches, the offspring will not be able to reach the sea because of the large amount of macro algae that they would have cross.”

The expert said that among the problems caused by these macroalgae is that they consume all the oxygen that is found in the sea and therefore the fish that are below the sargassum begin to die.

To the list of negative consequences, the affectations to the flora and fauna of the reef systems are added, which in the Caribbean represents the second largest in the world, since sargassum releases phosphorus, nitrogen and heavy metals, which deteriorate the quality of the sea water and cause profound damages in the marine ecosystems, such as coral reefs.
