In this lesson, students are reminded of the previous discussion about citizenship and the Sustainable Development Goals (SDGs). They learned that, as citizens of the world, including Molten Gozo, they have responsibilities in contributing to sustainability despite their youth. The focus of this lesson is on the seventh SDG, which highlights the importance of renewable energy sources like wind, solar, geothermal, and water energy. The instructor encourages students to consider how they can take action to support these goals in their everyday lives.
