The sea! Mystical, exciting, beautiful! Around two thirds of the earth's surface is covered by the sea. Logically, the sea is therefore an enormously important space for humans. It serves as a habitat, as a transportation and trade route, as a source of food or simply as a place for recreation and sport. And although the world's oceans play such an important role in human history, only around 5% of them have been explored. At the same time, the part that is already known is being excessively used and exploited to supply people all over the world with marine products, often at the expense of ecosystems and marine organisms! If that were not enough, the sea also serves directly and indirectly as a garbage can and catch basin for all kinds of pollutants. Whether heavy metals, crude oil, microplastics or any kind of waste - all of these can now be found in the world's oceans. It is clear that the sea needs our help! This exhibition deals with the topics of marine use and marine pollution in a very vivid way!
