When the cruise ship Costa Concordia ran aground in January 2012 with the loss of 32 passengers and crew the environmental dangers to the Tuscan coastline were obvious.

Julian Rush reports from the island of Giglio on the hopes and fears of local people and considers the risks that the new generation of super-size cruise liners pose to some of the most beautiful coastlines in the world.
