Return ebb and flow must save Grevelingenmeer

Experts speak of an ecological disaster in Dutch waters. Due to lack of oxygen there are places where life is no longer possible, the so-called dead zones. But a solution is being worked on: reducing ebb and flow by, for example, cutting holes in the Brouwersdam.

Especially the Grevelingenmeer and Volkerakmeer benefit from this. There the oxygen content in some places is so low that all life there dies. And also not returning. In contrast to places where there is still tide, such as the Oosterschelde.
