How does what we eat affect the environment?

I present an activity designed to raise awareness of the relationship between the food we eat and climate change, aimed at a second-year high school class (15–16 years old). The activity is structured over approximately four hours of classroom work and two hours of homework. The first step involves reviewing students’ prior knowledge of biomolecules and nutrition, climate change, and the environmental cost of food. In class, different menus are then analyzed in terms of nutritional completeness and environmental impact. The activity continues with a home-based monitoring phase in which students record what they eat and evaluate their daily menus. This is followed by a collective discussion and analysis focused on identifying practical ways to make everyday food choices more sustainable. All activities are carried out using cooperative learning–inspired methodologies and digital tools.
