5.1 How sustainable is our current diet?

Information for Planning & Teaching

Background Knowledge

Different food, different impact

Along with varying impacts on human health, different foods have differing impacts on the environment. As shown in the figure below, the production of animal-based foods tends to have higher greenhouse gas emissions (orange bars) than plant-based foods—and dairy and red meat (especially beef) stand out for their disproportionate impact. Beyond emissions, it’s also important to note that food production places enormous demand on our natural resources, as agriculture significantly contributes to deforestation, species extinction, freshwater depletion, contamination, and freshwater consumption.

Lesson Timing

Student Ideas & Experiences

Reflection allows students to become aware of their current eating habits and gain a deeper understanding of the food choices they make. Reflection serves as a foundation for goal setting and action planning. Students can identify areas for improvement and set realistic goals for adopting healthier and more sustainable eating habits. It fosters a sense of mindfulness and responsibility in students as consumers and citizens.
