Political leaders, NGOs and scientific elites from the nine Baltic countries are meeting on Wednesday in Finland's capital Helsinki to take part in a Baltic Sea Action Summit on cleaning up one of the world's most polluted and poisonous seas.
The sea was used to dump thousands of World War Two planes, chemical weapons and even dead bodies.
The World Water Forum says all the Baltic states "are sinners" for dumping over the years tons of sewage and agricultural waste into the sea.
As a result, large areas of the body of water are suffering from eutrophication or lack of oxygen.
