Some say the cruise ships pollute the water and upset
the ecosystem in Venice's lagoons. Cruise ships may
also cause structural problems, a great concern to

other hand, however, visitors spend money in Venice's
restaurants, hotels, shops, and markets. This boosts the

city's economy and provides jobs for many residents.
