Day and night thousands of vessels are carrying vital goods to millions of people around the Baltic Sea. Almost everything we consume has been shipped on water.
However, large parts of the Baltic Sea are in distress. We have documented dead sea beds and suffering wildlife.
And when we took a closer look at the expanding cruise industry – we could not believe our own eyes.
Gigantic floating cities with thousands of inhabitants. All of them eating and drinking – and producing huge amounts of sewage and toilet water. But instead of using port facilities the cruise ships dump their toilet water straight into the sea.
So we tracked down the experts at the highest international level.
The whistle-blowers and the scientists who call for action and rectification.
Those who have made astonishing findings and drawn frightening conclusions.
