Based on current Spanish legislation and the goals of the 2030 Agenda, six sessions and a final task have been designed. This consists of designing a newspaper page about endangered species with a conservation proposal. The unit incorporates Sustainable Development Goals (SDGs) 13 (Climate Action) and 15 (Life on Land) and has Picos de Europa as its central theme, a protected natural area in the provinces of León, Cantabria, and Asturias. This proposal aims not only to teach linguistic content but to encourage students' critical thinking, as well as their motivation and connection to their local area.
