"Since 1998 (international year of the oceans) that oceans have become to be understood as a heritage for the future. And the most productive ecosystems on Earth are the coastal ones, because they provide us with essential services such as, water filtration, nursery grounds for fish, protection from storms, disaster risk reduction and another integral service - sequestering and storing ""blue"" carbon (CO2) from the atmosphere and oceans. Despites their benefits and services, coastal blue carbon ecosystems are some of the most threatened ecosystem on earth, with an estimated 340 000 to 980 000 ha being destroyed each year (numbers from “The blue carbon initiative”- UNESCO). The area of sea under the control of EU Member States is the world's largest maritime territory, it is imperative to raise awareness for the rapid degradation of coastal ecosystems caused by human impacts (urbanization, industry, sewers, fishing, agriculture, tourism and all kinds of pollution).A strategic partnership of citizen science research/action focuses on coastal ecosystems that are threatened by human presence is proposed by 6 schools implemented in communities in or near coastal areas, localised at natural reserves. Geographically each one is located at the coast of Mediterranic, Black, Ionian and Baltic seas and Atlantic ocean. The project coordination is made by an interdisciplinary team of teachers from different areas like science, geography, language or others, and experienced in Erasmus or other European Projects. The target students will be from secondary stage aged 16-19 mainly from general and VET science courses.Our compromise will enhancing a shared view on the European coastal areas through the following parameters: selecting certain biological and chemical indicators, such as the amount of blue carbon and the environmental quality of water in different coastal areas of Europe, building a database with the values collected in order to allow an effective European monitorization, comparing analyzing not only the evolution of the human impacts but also the effects of the measures taken to preserve coastal ecosystems. Being future European citizens, from different geographical areas, involved in analyzing and comparing the data collected and assessing the different levels of human impact not only will raise the scientific knowledge of what can be done in order to improve quality of life but also will lead to deeper involvement and care about preserving and contributing to a balanced ecosystem in coastal areas in this part of the world.There will be training activities for students and teachers about blue carbon and coastal ecosystems. Furthermore, science Lab activities and group activities will be developed to apply the knowledge acquired. Will be also developed thematic workshops, field trips, visits to universities departements, researches and results presentations, mapping activities, cultural peddy-paper, local excursions. Each school will be represented by 2 teachers and 4 students in each mobility. The theme of the project is current and promotes the importance and motivation of students in the learning process of STEM subjects. It will be an interactive way to teach students to make charts, data analysis, data presentation, research, drawing conclusions. Also, environmental education is the best way to offer equal chances for all students, even those with special needs or from all sorts of backgrounds and learning abilities.It is imperative to raise awareness for the rapid degradation of coastal ecosystems, starting from the younger student population to the older habitant of the community."
