The Black Tears of the Sea – The Lethal Legacy of Wrecks

52m 12s

More than 70 years after the end of World War II an oppressive legacy from the past overshadows the future: ships sunken in the war rusting on the seabed. They pose a threat that is still completely ignored. Lying on the seabed are 6,300 wrecks which together contain an estimated 1.5 to 12 billion litres of oil.The question is: how long will the oil stay inside? It’s a journey that takes us back into history, on perilous salvaging missions, to the ocean bed, and into laboratories, archives and government offices.
