PBS: NOVA Season 49, Episode 11 «Saving Venice» Aired: Sep 28, 2022 (United States) 54 min | Science, Nature, Documentary | TV Series (1974 - now) (ENG/SUB ENG) About: Built 1,600 years ago on a string of islands in a marshy area open to the Adriatic Sea, Venice is confronted with a multitude of scourges. Although in the 15th century extensive work was undertaken to combat the gradual silting up of the lagoon, this also resulted in more frequent flooding. Now a major travel destination, the Italian city welcomes millions of tourists every year, which further increases the risk of flooding: the huge wake of liners and cargo ships dangerously accelerates the erosion of the neighboring salt marshes, while the many motorboats speeding along its waterways damage the walls of the channels #Nature@zdenek1964 #Documentary #Science@zdenek1964 #PBS@zdenek1964 #NOVA@zdenek1964 #SavingVenice
