On April 13th, 2023, ATRAC held a workshop for children “Raising awareness of the importance of the sea” as part of the projects CASCADE and FIRESPILL. The workshop was attended by elementary and secondary school students from the area of Rijeka who are part of the association Center for the Culture of Dialogue in Rijeka. Through the presentation, students were given knowledge about the importance of the sea and the preservation of biodiversity, invasive species, the consequences of pollution of the marine environment with hydrocarbons and plastic, as well as the problems that such pollution causes to living organisms and how they circulate in ecosystems. The participants are also familiarized with the way in which they can react in case of spotting an oil spill in the sea, and what changes they can introduce in their daily life in order to contribute to the preservation of the marine environment.
