"Out of the Blue" is the inspiring story of the legacy inherited by the children of Cabo Pulmo. Once described by Jacques Cousteau as the Aquarium of the World, years of overfishing killed the reef and pushed its inhabitants to the brink of extinction. To get their reef back, the Castros—a family of fishermen family in Cabo Pulmo—chose to sacrifice their source of income and food by making a revolutionary yet dramatic decision: ban fishing in their own waters to encourage marine life to come back and take shelter.
