Heading to Venice? Don’t forget your pollution mask | Axel Friedrich

Venetians regularly protest against the huge cruise ships docking in the city, but mass tourism is not the only problem they bring - the toxic air they pump out is harmful to locals and visitors alike

If you're heading to Venice on holiday this summer, don't forget to pack your pollution mask. Worrying about toxic air might seem strange in a city with few roads and cars, but Venice's air carries hidden risks.

Every day five or six of the world's largest cruise ships chug into the heart of the ancient city, which hosts the Mediterranean's largest cruise terminal. These ships advertise luxurious restaurants, vast swimming pools and exotic entertainment - but keep quiet about the hidden fumes they pump into the city's air.
