Wednesday, 22nd November, our students visited the Sea-U Marine Knowledge Center and learned more about environmental issues affecting the ocean. They also worked with the UN Global Goals. Rubbish, wastewater and chemicals ultimately end up in the ocean. In the Baltic Sea we have had a long time problems with poisons like PCB and dioxin, while in recent years there have been alarms about microplasts, microfibers and drug residues. In the Pacific, it flows around large plastic islands of plastic, and if we continue as now, by 2050, it will be more plastic than fish in the ocean. Many of the animals of the ocean eat and are damaged by plastic bags, the strips of plastic bands and tiny plastic pieces are stored in their bodies. Another problem is the so-called ghost nets, ie fish nets drifting around and killing lots of fish and other animals. The synthetic materials are not broken down by nature, and the network can therefore continue to sail around year after year.
