To fight the bottom trawlers destroying his beloved Mediterranean Sea, an Italian fisherman realizes art can be the most powerful form of protest. Paolo Fanciulli tried everything to stop bottom trawlers from destroying the precious underwater meadows and corals of his beloved Mediterranean Sea. For 37 years, he’s denounced them publicly in newspapers, linked arms with environmental organisations and even attacked the trawlers with dinghies himself.

Yet nothing worked - until Paolo comes up with a plan to place more than 800 concrete sculptures on the ocean floor. The art doesn't just create habitats for the fish. It inspires a movement to save the sea from destruction.
