Sources close to the European Commission claimed that the Baltic Sea was among the most polluted bodies of water in the world. The marine ecosystem was under threat from several factors, such as pollution, poor management, overfishing, unsustainable fishing, and climate change. Therefore, it was imperative to stop the production of trash before it entered the ocean. For this reason, the countries of the Baltic region require high-quality education on environmental issues. By 2030, 30% of the Baltic Sea was to be protected, according to the European Commission and the Baltic Sea Action Plan (BSAP). The primary goal of the project was to educate young people on the relationship between decisions made in daily life and environmental problems, specifically the pollution of the Baltic Sea. To assist in achieving the main goal of the project, the following goals had been set: Raised awareness of the Baltic Sea pollution level and its importance; Identified the most prevalent negative consequences of people's environmental behaviors, as well as strategies to address them; Developed awareness of the connection between Baltic Sea pollution and related environmental decisions in different sectors. Promoted environmentally responsible behavior at the local level; Fostered a proactive attitude toward green efforts. Assisted participants in developing a sense of social responsibility toward environmental protection; Engaged youth in international discussions and decision-making regarding environmentally friendly actions; Kept youth active and assisted them in learning how to put ideas into action, enhance their social skills and multilingualism, and stimulate cultural exchange.
