Great Decisions High School: Sustainable Food Systems

The way we produce, consume, and waste food plays a significant role in climate change and environmental sustainability. This edition explores how food systems contribute to greenhouse gas emissions, the impact of food waste, and solutions to reduce our environmental footprint. With one-third of all food globally wasted, the issue highlights how composting, plant-based diets, and better food policies can make a difference. The discussion also includes policy debates on government regulations, school lunch programs, and consumer responsibility in reducing food waste.


Key Topics Covered:

  • Food and Climate Change – How the global food system contributes to one-third of annual greenhouse gas emissions.
  • Food Waste and Its Impact – The U.S. wastes over 400 pounds of food per person annually, contributing to methane emissions.
  • Meat vs. Plant-Based Diets – The role of livestock farming in deforestation, water consumption, and carbon emissions.
  • Composting & Food Recovery – How cities and individuals can reduce landfill waste and repurpose food.
  • Policy Debates – Should governments mandate composting, require plant-based school lunches, or pass stricter food waste laws?
  • Global Food Insecurity – How food waste contrasts with the one in eleven people worldwide experiencing hunger.

Why Teachers Should Use This in the Classroom:

Connects Environmental Science & Policy – Shows how food choices impact climate change and global sustainability efforts.
Encourages Civic Engagement – Students can explore policy solutions like food waste laws, urban composting, and school meal programs.
Promotes Personal Reflection & Action – Encourages students to analyze their own food consumption habits and consider ways to reduce waste.
Interdisciplinary Relevance – Ties into science (climate impact), economics (food supply chains), and social justice (food insecurity).


Tips for Classroom Use:

📌 Debate Exercise – Should cities require composting, or should food waste policies be left up to individuals?
📌 Case Study Analysis – Compare food waste policies in the U.S., Europe, and developing nations to assess effectiveness.
📌 Hands-On Activity – Conduct a food waste audit in the school cafeteria and propose solutions to reduce waste.
📌 Role-Playing Simulation – Students act as policymakers designing a national strategy to reduce food waste.
