The Balearic Sea is beautiful both above and below the waters. It is one of the most richly biodiverse areas of the Mediterranean. 20% of its waters are legally protected; It is home to more than 400 fish species; It provides 50% of all Spain’s Posidonia seagrass meadows; there is a resident population of sperm whales and dolphins; and bluefin tuna come here to breed. It is a source of leisure and happiness for many of us. It is the basis upon which the economic prosperity of these islands and people’s wellbeing depends.
