This activity is marked by the multiplicity of tools that participants have at their disposal and, with the participation of different partners, is presented as central to the educational programme. During the workshops, participants will be encouraged to discover marine biodiversity, as well as the main threats it faces, namely plastic. The ex-libris of this activity is the diving baptism. Accompanied by a certified instructor, students will explore what turns out to be a fully immersive workshop underwater, intertwined with the workshops on biodiversity and threats to the marine environment. In the pool, participants have the opportunity to face challenges that address daily difficulties of marine life, being an important component in raising awareness of current issues.
