Many Venetians say cruise ships and tourist hordes are killing their city - almost literally after one gigantic liner crashed into the harbour on 2 June.

Manuela Saragosa speaks to the activists fighting back: Tommaso Cacciari of No Grandi Navi ("No Big Ships"), Sebastiano Giorgi of Gruppo 25 Aprile, and Matteo Secchi who fears his home town is being steadily transformed into a gigantic theme park.

But it's no simple matter of simply banishing the visitors. Venice receives 30 million tourists each year - some 600 times the number of city residents, most of whom now depend on tourism for their livelihoods. Manuela asks Italian transport minister Danilo Toninelli what the government's plan is. Meanwhile, Jan Van Der Borg of Venice University explains why the economics of tourism is far more lopsided than most policymakers appreciate.
