The invasion of micro algae in the Canary Islands is not an isolated event. Although according to scientists, the appearance of cyanobacteria is linked to exceptional conditions resulting from a rare meteorological cocktail linked to El Niño, they have already appeared in the area.

Finally, it is considered that it has not yet been scientifically proven that wastewater discharges favor the appearance of microalgae. We do not know exactly what should be the scientific relationship to establish, if it can be highlighted that as water has more pollutants such as nitrogen and phosphorus the proliferation of algae in the water has exploded exponentially. chance?
