The Costa Brava (“Wild” or “Rough Coast”) is a coastal region of northeastern Spain, very touristic area due to its known wild beauty. When here, trying one of the many offers for diving or snorkeling on your own, you will be surprised by the thousands of fishes around you, all seems indeed wild and unspoiled! But to remember that marine ecosystems are very fragile in general, and an impact on the smallest of species may have an impact on the whole ecosystem! What governments can do to help, in general, is controlling/regulating fish farming and fishing industries, put in place efficient recycling policies to avoid plastic ending up in the seas and oceans, as well as limiting/reducing the use of industrial fertilizers through regulations, prevent untreated wastewater from being channeled into rivers and seas and restore wetlands and natural coast defenses which help filter nutrients out of the water before reaching the sea! What you can do is: to recycle, to consume pesticide-free products and to respect the environment in general!
